'Predator mindset' = track down, stalk, pounce, and kill... That's basically an assassin, which is stretching the concept of 'self defense' to an Orwellian degree.

An analogy I've heard that I like better is a cornered cat. Like the intro on this website (www.corneredcat.com - I'm not actually into guns, but if was, seems like a decent website).
