Wolverine took a vow of non-violence?!?! How the heck did that happen?!
That's almost like Ron Jeremy taking a vow of chastity at the beginning of a movie or Jack Black vowing to be completely serious at the beginning of a movie. What a really stupid idea.
I actually thought it was a pretty good idea, myself. I think they might have overdone the reason a little, but the concept in of itself of Wolverine doing something like that was pretty interesting to see.
