Vegeta is a complicated person. He's likely the most complex character in DBZ truth be told. I think a great deal of this bodes well in the event that you consider the way he grew up. Vegeta was the ruler of a pleased warrior race and before he truly had an opportunity to lead, his claim was stolen by Frieza and he fundamentally turned into a slave. He watched his race diminish in subjugation until all the pride he'd been advised they used to have is gone. They are embarrassed and crushed by Frieza. Their whole warrior society is crushed, and as a ruler, Vegeta most likely thought of it as his obligation to keep that society in place. He fizzled, not that he could help it. He was only a youngster. Be that as it may, it bodes well then that Vegeta's whole life gets to be about only pride and quality. He conveys the heaviness of his whole culture on his shoulders and feels that he, as the sovereign of all Saiyans and his way of life's exclusive "genuine" survivor, must be the most grounded in the universe, since that is the best way to redress how far they've fallen and keep the universe's memory of their quality in place. He hates Goku for some reasons, however one of the greatest is that while Goku is a full blooded Saiyan, he doesn't know anything of Saiyan culture and has no appreciation for it. Since Vegeta's lost planet and its way of life means the world to him, Goku just irritates him since he basically couldn't care less. To the extent Goku is worried, there's next to no about Saiyan society for anybody to keep in touch with home about. In his brain, they were only a cluster of shrewdness rascals. Does this irritate Vegeta, as well as it likely makes him feel alone also. He's the main individual left in the universe who gives two craps about planet Vegeta. It resembles if the earth was crushed and you were one of its lone survivors, and you met another survivor however they didn't know anything about Earth or think about it. Would you be pissed? Another reason Goku irritates him is that everything is by all accounts so natural for him. Vegeta works his rear end off, yet Goku is constantly one stage ahead—only a tad bit more grounded. Goku can't be the most grounded Saiyan, for one since he isn't the ruler of all Saiyans, and for another, in light of the fact that he has no admiration for Saiyan society. Vegeta must be more grounded, in light of the fact that he is a "genuine" Saiyan and Goku is definitely not. This is something Vegeta discusses in the Buu Saga amid his battle with Goku, however I'm not certain how it interprets from the first Japanese. Be that as it may, in any case, every one of this is the reason Vegeta's continually discussing pride and quality and the glad warrior race and how he's the ruler of all Saiyans. It doesn't generally have much to do with narrow-mindedness by any stretch of the imagination. It's about safeguarding the memory of his home world so that everybody recognizes what they once were. In his initial life, it's what drives him to attempt and assemble the mythical serpent balls and wish for godlikeness, it's what drives him to need to kill Frieza, and it's what makes him appreciate killing individuals who are weaker than him (he's invested such a great amount of energy under Frieza's thumb that appreciates having the tables turned where other individuals are under his).
Every one of this progressions gradually for Vegeta through the span of DBZ. As others have said, Vegeta has thought about Trunks since he discovered he was his child. Be that as it may, Vegeta's association with future Trunks was extremely strained. The explanation behind this is much the same reason that Vegeta dislikes Goku. Much the same as Goku, Trunks knows nothing about Saiyan society or the pride of their warrior race. He is particularly an offspring of Earth in his dispositions. Vegeta sees himself as especially to be the last "genuine" Saiyan (the main individual with any memory of the planet and dependability to its way of life) and once more, he should consequently be the most grounded. Not even his child can be more grounded. His hatred for Trunks at an early stage accompanies realizing that Trunks, much the same as Goku, is more grounded than him regardless of the way that he doesn't know anything of Saiyan pride. He still, in any case, thinks about his child, and demonstrates that when he snaps and assaults Cell.
After the Cell Saga, Vegeta lives with Bulma at Capsule Corp and helps her raise Trunks while keeping on preparing at the same time. Through the span of these seven years, Vegeta's mentality toward Earth starts to change. He misses his Saiyan society, however living on Earth, he frames new connections with Bulma and Trunks and Earth begins to wind up his home. Though before he had no home, and essentially clung to the memory of one by attempting to be the most grounded in the universe, on Earth be finds another home which begins to supplant the old. At the point when Goku returns, Vegeta perceives how solid he's get to be and understands that he is overlooking his Saiyan legacy. He feels regretful for having discovered something of a home on Earth, and this is the reason he permits Babadi to discharge the malice in his heart. He needs to obliterate his connection to Earth since that connection makes him powerless and implies he is disregarding his obligation to safeguard the Saiyan society. That blame, and additionally the disdain he's been working toward Goku for being so solid thus unappreciative of their home world gets him in a battle with Goku—a battle he should urge Goku into at any expense. When he fires on the Earthlings at the competition, he's essentially attempting to annoy Goku by annihilating some portion of his reality's kin (feel my torment sort of thing) and in the meantime, let go of his own connection. For all he knew, he could have executed Bulma or Trunks with that impact. With the malice in his heart at long last discharged, he can do such things and his attention is back on the pride of the Saiyan race. Amid his battle with Goku, the greater part of the indignation Vegeta feels toward him at long last turns out, and them two at long last... all things considered, discuss their emotions - discuss Earth and planet Vegeta and what it resembles to be in every others shoes. Basically, they go to a comprehension through their battle. Goku comes to regard the way that Vegeta feels (and even wins a little Saiyan pride of his own) and Vegeta at long last recognizes what Earth intends to him. At the point when Buu is discharged, Vegeta thumps Goku oblivious in light of the fact that he needs to be the one to execute Buu, yes (pride if the Saiyan race). However, when he understands he can't win, and sees Trunks awakening him, he understands that Trunks is going to kick the bucket if Buu is not vanquished, thus will Bulma and everything else he's come to acknowledge about Earth's way of life. He recognizes that Earth has turned into his new home (regardless of the possibility that he will dependably think about his Saiyan legacy) and he explodes himself to spare it. Vegeta still did a ton of terrible things, and the DBZ the great beyond is a karmic one. That is the reason he is not viewed as "great." He has murdered excessively numerous innocents, and his great deeds don't exceed his terrible ones. Karma is by all account not the only type of good judgment in the DBZ universe be that as it may, and the Eternal Dragon's judgment of Vegeta mirrors this reality. He judges Vegeta in light of the virtue of his heart as opposed to his past activities. It's about the now.
For me, the minute when Vegeta really, genuinely, turns out to be great is amid the battle with child Buu. He is watching Goku battle, the individual who speaks to the greater part of his injured pride, and he at long last gives up. He at long last recognizes that Goku is the best. This connotes he has at long last (after years) let go of his should be the most grounded, and the only thing that is in any way important is that they spare their new home on Earth.
Vegeta will dependably be pleased and bombastic, and he will dependably need to be the best, yet the Vegeta we see today is not all that self-important (perceives his shortcomings) and he will do whatever he needs to secure what he's come to think about—sing a bingo tune to keep a divine force of decimation from getting irate around a pudding cup.
