... assuming you live in a western society, how do you feel about the hundreds of thousands of middle eastern people we kill (with the U.S. doing most of the dirty work) so you can have cheap oil? Do you think about it?

I'm not trying to be confrontational (though obviously this is a loaded and maybe unfair question). To me, that knowledge leads me to the conclusion that enjoying the fruits of civilization requires killing. That is, the line is between purposeful versus gratuitous killings. So I'm untroubled by killing mice for medical experiments. I'm curious what thought process allows people to register the killing of mice. Do you live in a state of distress about your own existence?
