out of character. Wouldn't he have been at least a little mad?
I mean, he could think something like 'I can't even KILL him

I got the idea that after it was done, Ryouga wasn't quite so sure he 
wanted to kill Ranma anymore.  Didn't he run off to wander around in 
remorse afterward or something..?
