He lost the use of his right leg, so he physically couldn't.
hes got his arms still....
Yeah, but a big part of being a hitman is mobility. It'd be pretty tough, if not impossible, to be a hitman from a wheelchair. You gotta be able to run, man.
i dunno, i see him standing in the manga. didnt he get maybe a fake leg? even if he is slowed down, isnt it better than risking someone you love?
I dunno if he really loves him; it seems to me more that he's just using him in some weird fucked-up way. Also, walking with a fake leg is hard! He's probably really slow. I doubt he'd risk his life when he'd absolutely fail.
why doesnt he dirty his own hands? why destroy the uke like that by making him be the killer?
