Have had dark thoughts of some sort. I am reminded that I am an animal with the benefit of societial carrots and sticks to have raised me in a way that is morally good. But deep down, given a different upbringing, I am probably capable of things I would find appalling and shameful.

I feel like every guy has had those kinds of moments. I feel like it is a slightly rarer occurrence in women given they have less of the horny rage hormone of testosterone. Obviously your milage may vary, but those teen years are a hell of a ride.
