Hmm... "taking over the world" part is okay for me, because that would show anyone who doubted him in his childhood that he cannot be doubted. Kinda basic, I know, but alright. But killing everyone? Lame.
I don't know how i feel about this, i mean yes public humiliation to a kid as fucked up as Fukubei was can cause a serious damage in his brain and make him believe that all humans are pieces of shit that don't deserve to breathe.
but on the other hand when you compare this to Johan's motives/childhood, it becomes very laughable.
