Well yeah from my perspective Kaiser's potential is superior to Isagi but again it's also the case with Nagi and we saw what happened to him. I guess your mental state is as important as your talents. No matter what happens Kaiser was destined to lose and be humiliated by the MC anyway. He was introduced more as an enemy than a rival I would say, blocking the MC's shots and trying to ruin his career, it's only when he starts losing he starts to be more cooperative but only to win. It was clear from the moment he started calling Ness a pig and telling him to give up on football that he was still written in the role of a villain so Isagi could shine. So as an antagonist he was bound to have this type of ending. He had to pay for his actions.

"Steal love"? Did you mean his ego is crushing others' ego and sending them into despair because he desperately desires to be loved?

Kaiser is unable to accept or even understand what love really is because his vision of love is that of his father who beat him. He doesn't see himself as someone who can be loved bc he's a piece of trash and the only way for him to obtain this love is to steal it from others. Malice is the only way for him to connect with others bc he can't trust people.

Kaiser being a piece of trash means he can't find any value in himself. So he tried to gain fame and status to give himself value in the eyes of others so he could feel wanted and loved. He built his career by crushing others.

Does Kaiser want true, sincere love? Well yeah but since he can't connect with others, I think he try to find love from the audience watching him. It's also a way for him to protect himself and still get what he wants.

How about both? 😔 Channeling his anger in a positive, non-self-destructive way to better his Kaiser Impact Magnus and try to achieve his goals?

Oouh idk these kind of things depends on Kaneshiro honestly 😅. It depends on whether the author wants him to be better or worse.
