While it may seem that society today is one major horrid violent ****-wad, keep in mind that, at no other time in history has human life and individual rights been so valued by so many. Just 50 years ago, it would have been considered ridiculous to give a tin shit about the treatment of captured terrorists. (I don't give too much of a shit, myself, but I respect differing opinions.

) Our own prisoners are given incredible rights these days, they have access to food, books, fitness, and television, things people in 3rd world countries would kill for.
And if you think about it, here in the western world it is extremely uncommon for anyone to actually die or suffer horribly from hunger or freeze to death; a person would have no just plain not seek help at all for that to happen, as we have a system that provides health care, food, and shelter to those who seek it.
Now I have been sick to death for the past few days about those kidnapped kids, one of whom was killed, both were repeatedly raped, and their family was brutally murdered while they watched. But go back about 300 years, and you will find that this sort of thing commonly happened to any village who has the misfortune of being invaded, even by so-called "civilized" armies.
Finally, there are many places in Africa where selling your children into slavery is still a valid debt-repaying system; where a man from a powerful village sends thugs to kidnap a woman he wants as a wife, and these thugs have no problem murdering her family and raping her on the way back to the "husband"; there are places in India where, as soon as a baby girl is born, it is dashed upon the rocks because they only want sons, and in some places in the Middle East a person can be stoned to death just on someone's word against them.
The leaders of these places don't want our help, they don't want us in there, because we might put a stop to their fun. Cruelty is their way of life and they know it's wrong, but boy do they have fun just being able to kill and maim and rape anyone they want (not just women). That's true evil- just as that guy who got those kids, and the ones before that, and the ones before that- and if people weren't so damn concerned with the "human rights" of terrorists, sexual predators, and the like, we wouldn't be in this boat.
Therein lies the irony. Sorry for the rant- I have been stewing about things for awhile, and you brought up such a good subject.
