I guess my viewpoint is this- physically hurting people is outside the bounds that we try to establish for ourselves and society.

We have laws against it.

So, If you are so detached that you don't realize what you are doing is against the law, you are crazy.

If you know what you are doing is against the law, then kill yourself because you don't want to pay the price or are that thatched in the head. You are crazy.
