Dan, Thanks for w wonderful, thoughtful post. I agree that the young fellow you describe is not moraly justified in doing what he does, but on a practical note, we must find a way to not create an environment which creates such people. I don't think Bin Ladin is pshcyotic, rather I think he and his killers are sociopathic. There is a huge important difference, he does not hear voices in his head likely which can be cured by anti-whatever drugs. Rather he hears crying in the night. In fact, many who follow him don't realize that alot of the crying in the night, is caused by their side as well! But, there we are, we have to do something to aliveate suffering if we wish to be safe, consider it a tax. We tax to take care of the poor, so that they don't get the plague and spread it to us... (well, I am poor so I feel funny writing that last sentence!!!) But, in a practical sense, we share because what goes around comes around, even back in Hillel's day he saw that, "do nothing to another that is aphorant to yourself, that is the Torah and the rest is comentary". If in fact we lived to a small degree that way, spread love as fast as we spread sit-coms and McDonalds, we would sleep safe in our beds.
Cheers Larry
