I would argue that a dangerous or selfish feeling is still legitimate. You feel what you feel, and it's important that that be acknowledged. That doesn't mean that the feeling should ever be acted on, or should be celebrated. And it doesn't mean that you're better off keeping that feeling; it might be worth taking steps to attempt to get rid of it. But that doesn't mean it's not there.

I guess my last paragraph doesn't really address that kind of feeling; it's sort of on a different topic.
