You hurt someone intentionally, you should not be breathing free air for a while.
Genuine question; is that only physically? If I like causing people pain and anguish and suffering, and my weapon of choice is words, should I also be incarcerated because I hurt people intentionally? I tend towards not giving people a free pass simply because their weapon of choice is words, but (amongst other things) the US has a reputation for being very permissive with the spoken word.
