This isn't exactly what I've observed over the course of my life. It's people not feeling in control that coaxes them into doing bad things: at least then that they feel powerful. Following higher codes - of honor, of ideals - is really hard, and humans are really brave for doing it, because it's so goddamn easy to fall through the cracks. It's for the same reason that people want to cut themselves: at least they can control that about their lives, which, by that time, are usually shit. Environment might encourage or discourage people taking control over their lives, but it can't be the source.I often fantasize over the idea that all people are good and it is their environment that has coax these less savory traits to the forefront of their personality.
