Cover art for Soil lyrics by System of a Down

I was giving it some thought, and I think the meaning I draw from "Evil lives in the motherfucking skin" is that 'evil' is a surface phenomenon in the way it manifests. Ie, you can be a bad/evil/ugly person inside, but that only exists in reality (to other people) if you project it outwards (to the skin).

You can be 'evil' inside, but if you control it and don't project it outwards, then to others you are not evil. Likewise, you can be 'good' inside, but if what you allow on the surface is evil, then that's how you present.

I think it's about the internal/external duality of concepts like good and evil and asking a question of: are you what you think you are or are you what others think you are, ie are you actually what you present to others?

This in the context of more extreme external projections that manifest from things like psychological illness makes a lot of sense. I often wonder whether people that are psychologically ill (with things like personality disorders etc) are actually good or evil inside, because if you judge what's on the surface, they can seem pretty evil.
