Earlier quoted context omitted.
My little sister just got into with me on facebook about how it is perfectly ok to torture our enemies. That's just the last straw for me. I would never have someone in my life, family or not, who would think raping people is acceptable. This is even worse. Even our enemies shouldn't be raped/tortured.
But killing them is ok?
On the other hand, torture isn't something that people do because they feel they have to, but rather because they can. Since all the accumulated evidence to points to it being a poor way to to gather intelligence information, it's hard to avoid the conclusion that it's just way of being vindictive or sadistic instead, something that we find deplorable in other contexts. I think it's considered deplorable because such feelings are quite common but the majority of us make the effort not to act upon them.
