I not even going to begin to go into that.
I'm going to let that sit.
I like enjoying fiction.
To the bolded, it actually seemed like this was talked about and the kuvera business withe their parents, just off screen. Maybe its just me but it was strongly alluded to kuvera and batar jr had beef with his parents for a while, and there was a whole host of shit said that didn't need to be shown, because isn't that important.
He was willing to build a death bot, and lock up his family.
He's far past the point of getting over it, he needs psychological help. Things are more complicated than just getting over stuff, I know its strange, but people don't just magically get over shit.
It might have been like every villain motivation in that show.
