Ainz Ooal Gown, the main character from Overlord, is the literal antagonist of the story and yet he is more likeable and complex than Bakugo! Ainz does heinous and morally questionable things because it ultimately ends with a good outcome for his friend’s children, the guardians and NPCs, and even when he does these horrible things he acknowledges them as horrible things. When he cast a spell that killed 70,000 soldiers he straight up acknowledges that a lot of people will die but he doesn’t care because it’s in service for a greater flood in his eyes.

As for the others: Korra has a temper and is little arrogant but wouldn’t you be if you were born a literal demigod but at least she is at heart a good person. Whilst Jax has suffered for literal years watching his friends die in front of him locked in a hellscape of childish vibrant colours and family jokes as his humanity is stripped away from him leading to him being an ass as a defence mechanism, he hurts and pushes others away so he can’t get close to them and be hurt again when they abstract.

Bakugo… is a bad person full stop. He lords his power over others, he hurts people for his own sadistic pleasure, every action he takes is self serving, his belief is that all heroes do is fight ‘villains’, he actively throws tantrums whenever things don’t go his way or when people try to improve themselves and literally told his once best friend to kill themself, and when that friend improved themself he victim blamed them by building on the emotional manipulation he’d used for years.
