I guess it’s because Nappa did most of the gruesome stuff to the Z fighters + He killed Nappa + he never really killed a Z fighter directly + he was brutal to Freeza’s soldiers + any death he caused in the Buu Saga was straight up meaningless in the long run because we have the Dragon Balls so dying never felt as serious anymore but the BIGGEST reason why Vegeta’s unlikable morals and personality are glossed over is because, in my opinion, the fucker never stops getting humiliated. For all his smug posturing, he gets his ass beat. Frieza. Android 18. Ginyu Force. Cell. Kid Buu.
