I guess I should make explicit my general assumption that we are not talking about psychopaths given the overwhelming odds that a given individual is not a psychopath. That said...

> If the idea of choking women to death makes one feel excited - no it's not natural or valid to feel that emotion, they have serious problems.

I disagree. That is surely a natural and valid emotional response for whatever reason this hypotheticals individual feels it. Yes, they also surely have serious problems but I contend that said problems are obviously what lead to this "very strange" emotional response. Their problems are also valid, regardless of the personal damage (read: devoid of outward violence) they cause.

In this case, the response might affect their behavior such that they actually do it and that would obviously be tragic; that behavior is not valid regardless of the emotions (or lack thereof) which motivate it. Otherwise, speaking of their emotional response, I don't see a reason to condemn them for a reaction they have such little control over.
