now yall wanna murk my man goku?!?!?! lol come on...he's saved the people/planet/universe time and time again...if he wanna have a tourney to find out how strong he is, let him....he doesnt know about the loser's universe gets wiped clause, lets see how he reacts when he finds out...once he hears it, i think his dumb ass gonna challenge the zenos lol....
also: blaming him for cell? vegeta has more sense? lol what?!?!?!...seems yall cats forgetting it was vegeta that let cell get to perfect cell in the first place cause he was overconfident...and like usual, it was goku and his fam that had to clean up the mess....just like with frieza and buu....but yall wanna end goku?....lol get outta here....
Even letting the Cell saga slide (because nearly everyone made at least one tactical blunder in that story), Vegeta's arrogance, pride, and bloodlust got him killed and resulted in the annihilation of the human race, and the complete destruction of the earth. If Vegeta had never given himself up to be Babidi's puppet, Buu would have never been awakened.
EDIT: Although to be fair, Goku was dumb enough to go out of his way to rescue Dende, Mr. Satan, and a DOG over Piccolo, Trunks, and his own seed (Gohan and Goten) before the planet blew up.
