No, I usually have a talk to all the people I have disagreements with. Find a common ground and maybe we'll turn out to be good friends.
If a human disagrees with you, let him live. I have thought about what it'd be like. Getting into the head of a sociopath, no empathy. Though too dirty, too draconian. Got my own life to live rather than a false sense of "control". I just wish others would think the same, but its FEAR of them why you gotta prepare to kill yourself. But a PROFESSIONAL killer, now ....
Most men have a natural tendency to think they're capable of supreme bad-assery given the right situation. ...but so many crumble when they finally get to that situation.
