I think your main draws are instinct, intuition and empathy... those things that you can't really practice.

If someone's carrying a gun or a knife it's not a nice thing. They aren't going to feel that comfortable with it. It's a scary position to put yourself in. You don't choose to do that unless you feel there's absolutely no other option and you're forced to carry a weapon in order to protect yourself.

It's much easier to have something that's absolutely definite and has a definite identity, rather than a really generic role.
