And that is where you are wrong. Being born with that condition means you do not know it is "wrong" and thus you are not "evil". It is just compulsion beyond your control and you don't feel any guilt. Addicts on the other hand DO feel guilt, just that they can't do anything to stop themselves. That's where insanity comes in. True insanity means you no longer have mental inhibitors and thus do what ever you think works no matter how cruel or extreme others think it is. That's why I love psychopaths. Sorry but that argument is flawed. And son of the director is an example? uh... he isn't an infant and you probably haven't met him or psychologically analyzed him prior to his death so you can't really judge. And quite frankly I don't see the big deal about him doing that. Motives aside, at least he ended the sin along with himself.

Like I said before, what judges you is how you take it. If you find genuine pleasure in it despite having the means to avoid doing such, that makes you evil. This aspect can come at any point in your life. However this all works according to interactions. Being a SM doesn't mean you are evil, however if you try to satisfy yourself without consent of others, then you are only looking for personal satisfaction and don't care about destroying others which I might add is not accepted to such a degree since man is a social animal and social groups everywhere in the animal kingdom do not tolerate such. Basically it comes down to that in terms of social behaviour of course. We are genetically organized in a certain way. Going against that means you have a death-wish or no longer adhere to the unspoken rule of living beings which is to survive and reproduce and then ensure survival of the spawn.
