I remember reading its manga and also dropping it the moment he killed his father. I know he's scum, but killing people who trust you with their lives is another level of being scum and evil. Seeing him die pathetically seemed satisfying because he totally deserved it. I mean... he's already living a good life before, yet he chose to be greedy and want more out of his already fine life. He wanted to play god and put justice in his hands while killing also innocent people who came in his way to his so-called justice. It's sad to see him go down that way, but like I said, it's also satisfying at the same time.
By the way, your drawing was really neat. I can't really draw without drawing many guidelines and line shading, so it's cool to see people who draw with minimal use of lines.
