Self defense is about defending yourself from those who would initiate force or the threat of force. We would all like to live in a nice rosy world where we roll around on gumdrops all day long and love each other, but we don't. We live in a hard, crass world where predators roam, and I propose that defending myself, by whatever reasonable means I deem necessary, is a moral obligation.

If "self-defense is about killing", do you make any moral distinction between a murderer committing wanton slaughter, and a woman shooting and killing an attacker that surely would have killed her?
