This is a very interesting conversation. If I may, let me put in my .25 cents. .
Back in my early twenties, after my first real long term relationship had ended, I had a tough time getting back into the whole social scene, but eventually I did. One night, after having a relatively enjoybale night with friends a bar in Boston (I live about 30 minutes north, so I drove into town), I left at closing time...yes alone...get your minds outta the gutter, and started to cross the public gardens, because my car was parked on the other side. Half way across, a group of drunk men (I won't say straight because I don't to insult straight people by calling them that), started to follow me.
Eventually they cornered me in a dark part of the park. I was beaten and raped and left there. Here's my question. If I had the ability, after they had finished with me, to get up and kill each one...would that not be capitol punishment? I am no longer defending myself, I am exacting revenge, but...am I entitled?
