Actually, if Polestar were a true psychopath, he wouldn't ask about how to become desensitized, because he would have been born that way. It is possible that he simply has psychopathic tendencies, however - which would allow for some sensitivity to the pain of others.
What an unusual thread - it's adding a quirky flavor to my morning coffee, to say the least...
To answer your question, Polestar, a good way to desensitize yourself to violence is too simply pretend that anything unpleasant you see in real life is actually being viewed on your internal television - you separate yourself from what is happening thereby. (similar to how photojournalists 'distance' themselves from what they are photographing war or famine, etc.) We in America who watch violence on tv or in video games are already partly desensitized - we just don't normally realize it.
One problem with picking off the inhabitants of an ecovillage or whatnot is that once you kill the 'producers' off, the entire reason that you attacked the settlement will disappear - it will stop producing, and its supplies will eventually be exhausted. You would have to keep moving in your parasitic quest, killing off more people to sustain yourself by taking what they have. Eventually, luck would turn against you and you would be killed in turn, especially if there is any communication between areas whereby villagers could warn each other of marauders in the general area.
Sure, you might succeed for awhile, but the odds would be against you in the long run.
You say you are homeless - what are you doing, sitting around in the public library on their computers to talk about this stuff? A cyber cafe? If you want real life experience of desensitizing yourself to violence, why don't you spend some time in the nearest gang-controlled neighborhood and watch what goes on there?
