I've got it. I've figured it out. (maybe)

What triggers active predatory aggression is flaws and the desire to exploit them. It doesn't really matter what the system is, which is why the feeling is the same regardless of whether it's exploiting a hole in someone's argument during a debate, finding your way through a cave system, or noticing a security flaw in a bank. It's seeing that angle. Do other people get this and just not act on it because of remorse or whatever? Or do most people not get this sort of feeling at all?

I've been trying to understand why I'm prone to sudden aggression at times, and I had this thought. I'm not sure if anyone else will find it enlightening, but make of it what you will.
