roll, i guess you don't know KEN that much by what you are saying !

example...
you say he is too lazy to go into evil...
but then again, i never saw someone that caring about fighting and friendship then he does ! he is lazy, but as soon as it comes to his friends, or family... he canmot be more into it then that ! so by definition your explanation doesn't work !

also... he got a family and he knows that fighting is his way of protecting those he loves, friends and family ! so he has a pretty damn precise idea of what becoming evil would get him, and that he doesn't want to ! that's why he will never turn evil. but, you might say that in a fight, he fights like he was the devil and gives no chance whatsoever to evil doers !

same goes for GEN, he fights agianst EVIL without giving them any chances. same goes for dhalsim when he fights !

see my points...
again, KEN is lazy when not engaged in a fight, but once he is locked in for the kill, he gives it everything he got and is no longer lazy and go all out on his enemies !
