To answer Umiman's question in the first post, I most likely would NOT sell my soul, because all the literature and entertainment I've ever seen on the subject indicates that the Devil will always screw you somehow, if you sell your soul for riches, you won't get to enjoy them, or if you sell your soul to get Superman's powers then the Devil gives everybody else a gun that shoots Kryptonite bullets or whatever. If I was in the situation of having a sulfur-smelling guy with horns and a tail wanting me to sign a contract in blood, I would negotiate with him for awhile, find out what he'd give me and what he'd expect in return, then turn him down and just walk away, and yet still get something that would be priceless to me. The fact of the Devil showing up with a contract is proof of souls, and depending on how the negotiations go, it might also be proof of an afterlife and proof of a Supreme Being. Having something that literally nobody else on Earth has is quite a prize, and all I'd have to do to win it is talk to the Devil for an hour or so and not get tempted.
Now, to discuss my own evil, I consider myself a moral person, but by society's standards, I'm probably pretty evil. Okay, you know who Fred Phelps is, right? Well, my dad was a helicopter door gunner in Vietnam, and if Fred Phelps or any of his brood show up at my dad's funeral and start shouting across the street through a bullhorn about how, "(Bromor's Dad) is burning in Hell because he fought for the homosexual states of America", then my response will be to pull out my trusty Gerber Gator Serrator, walk across the street, and start cutting until those Westboro scum look as ugly on the outside as they look on the inside. And I'd honestly expect a medal for that, too, not some pantywaist "aggravated assault, attempted murder" bullshit. Intellectually, I know that attacking somebody with a lethal weapon is considered an evil act and that I'd go to jail for it, but I can recognize that in that situation, I'd suffer a moral disconnection between what I know and what I'd feel. Heck, I'd probably physically assault WBCers if I was just passing the funeral of some random stranger and I saw them hanging around.
Purely hypothetically (that's my story and I'm sticking to it) I'm okay with, you know, just supposing that you saw a car with a "Truth Not Tolerance" bumper sticker on it, well, you could freeze a water balloon and then peel the balloon off of it, and then chuck the resultant frozen orb through their windshield. Hey, if they don't feel that they have to tolerate my beliefs, why should I tolerate theirs? They picked the game, I just (hypothetically) played it with them.
I also have quite a bit of sadism in me, but that's material for two other topics. I mean, I didn't even personally lose any money to Bernie Madoff, I didn't lose any relatives during 9/11, but if I could get ten minutes alone with Madoff or Osama, I'd walk out covered in blood and I'd enjoy every second of it. Does that make me evil? I honestly don't know.
