The difference between ethical atheism and nihlism is that ethical atheists have more faith

[Question Mark]

Genuine question here, not poking fun or anything, but are you of the opinion that "evil" and "sin" are forces, or energy, or something of that nature.

Not at all. I'm from the school that evil isn't really anything at all. It's the "absence of the good that ought to be there." For example, empathy is a good thing. A psychopath lacks that good. It's not that the psychopath has an evil force inside him, instead he lacks something. So when I talk about sin and evil destroying the soul from within, I'm thinking of the murderer who loses a little bit more of his conscience with every person he kills. Or the rake who slowly loses his capacity for true intimacy the longer he keeps whoring.

In fairness, there is a legitimate and demonstrable negative effect on society from those who lack the evolutionary empathy trait. The only debatable part is if, lacking that empathy, did they have any conscience to further lose.
In fairness though, they must be stopped. It's not healthy to have murderers about. Nympohmaniacs though, I can sympathise with them. Our species is born with an innate need for sex, and some people have more addictive personalities than others.

I went without any sweets for a whole 3 weeks. Bam!
