I am a person who sees horrible things like what happened on 9/11 or what happened to Nick Berg (I made the mistake of watching the video) and feel that those people responsible deserve to be eliminated from the population. I do not feel like they need to be tortured or made to endure a painful death. Quick and painless is fine as long as they are no longer around to take out innocent lives.
I just don't understand how these people derive satisfaction out of causing pain and suffering. My lack of understanding applies to the Americans involved in POW mistreatment so please don't think this has anything to do with nationality. I just don't have it in me to fathom someone being able to slowly hack someone's head off with a knife.
Having said that, I am sure that if someone did something horrific to someone I love, I would probably want to see them suffer. That suffering doesn't have to be physical though. I could deal with having everything they care about taken from them and being reminded of what they did every day of their life.
Does anyone understand how anyone could do such horrific things?
