Are you saying you don't think there are people who like being evil? That seems naive. For instance, how do you suppose the hijackers on 9/11 felt in their last moments? ....
So, I'm not quite sure what your point is. If you think that there aren't plenty of people in this world who like their evil ways and would just as soon eat nails as change them, then I'm afraid you're quite naive. If that's not what you mean, then I'm not sure what you're getting that.
As for religion, I don't expect that I can get my point across concisely, so I will leave it at this: I believe my religion is true. If that makes sense to you, good, if not, I don't want to steer this thread completely away from the story by going into it.
We seem to have two discussions going on here, so I'll try and handle them one at a time. I'll start off by saying that I do respect you and your opinions, even though I disagree.
I don't know whether or not everyone wrestles with their demons or not, but I do believe that people make choices for reasons that, to them, seem reasonable, logical, and moral. I'm not a moral relativist who believes that any one definition of right and wrong is as good as any other, but I do believe that we need to understand people's motivations in order to help prevent immoral acts in the future - from them or from others.
The 9/11 hijackers are actually an example of which I was thinking. I am a New Yorker and, while I didn't know anyone killed in the attacks, I did know people who worked in neighboring buildings, was at site myself a couple of days after the attacks, and worked in a situation in which many of my peers and co-workers were fearing further attacks. The whole event felt very personal to me. That being said, I don't think it accomplishes anything to say that it was an act of "evil". I believe that Osama bin Laden had reasons for what he did that made perfect sense and were perfectly moral in his world view. Part of it is misguidedness, part provocation, and part pure religious fervor. Part was certainly the idea that a sneak attack against soft civilian targers was the only way he COULD hurt such a militarillly superior enemy.
None of the excuses the 9/11 attacks, but it does set a framework in which the government could work to either sell our soldier's presence on the Arabian peninsula as a service to Islamic peoples or to get out of there, where we could reach out to enemies in a way to assuage their fears, etc. These ideas may or may not work, but they would be constructive ideas. To label the hijackers as "evil" as if we were attacked by Sauron or Voldemort denies the existence of reasoning and makes it that much harder to work for a solution. Why was the killer in the story a killer? Was he economically disadvantaged? Surrounded by career criminals from a young age? Feel powerless for some other reason? To say that he killed people because he liked killing people strikes me as reductive. It's more constructive to look for the reason he liked killing people. In short, my point isn't that there aren't people who wrestle with their choices, it's that only the very rare true sociopath sees himself as evil.
So far as your religion is concerned, I understand that you believe it to be true. Everyone else with a religion thinks theirs is true, and atheists think they're all equally false. With all equally unproven and unprovable (with the possible exception of atheism, but that's another discussion), I think it unfair to expect others to accept your belief as a cure for society's ills.
