Not sure I agree with you, I have always found it to be very relaxing.
Pleasure helps you to relax. If you feel sad, then it would be better to just knock down some drinks over torturing someone.
I've seen a fair share of people getting tortured for no good reason. My brother liked to torture people because it was simply another escape for him and his buddies. He and his friends got sick pleasure out of it and I'm sure it was relaxing to him too. Is he like that still? No.. He knows better now.
Maybe learning to play a guitar and writing music would help people to honor a loss, rather then just stooping to the level of some sick asshole.
