Now you're scaring me, dude! The only type of person I think I could whack would be, say, some pervert or nut who hurt my kids. Okay, maybe some of those on death row, I'd gladly throw the switch myself (or should I say, inject the needle?). I.e., I might could summon the callousness or courage to do away with serious criminal vermin...and even saying that, I can't be sure I could, when push comes to shove. Naturally, I could during a real war. But to whack some stranger--maybe even my best friend--just because a "boss" tells me to? Can't do it, man.
