I would add, though, that many aspects of human nature Satanists don't have a problem with at all. Most of the "dark" (or traits labelled as dark) things are not seen as things to suppress and control, but to revere and indulge in.
The line, as it were, is different. The line between indulgence and compulsion is different. Responsibility is different. Guilt is different.
Exactly right. And, that's why we prefer channeling desires to either suppressing or repressing them--because once an emotion or instinct is expressed in the right place at the right time, it can become something immensely positive and incredibly powerful. The urges themselves are nothing to be feared.
Reason being that I find myself willingly duty-bound to my family and friends (and I have very few friends). And I don't find fulfilling my duties to my family and friends to be unpleasurable. In many instances, my interests align perfectly with those of my family and friends.
In cases where there isn't perfect alignment, I can at least say that the caring I feel for my loved ones outweighs, in the long run, any fleeting irritation I might feel over having to re-juggle my schedule or temporarily forgo some pleasurable activity in order to help them out.
And, in those situations where the burden on you is greater than the burden on them, there's always that lovely two-letter word to save the day.
