Murder in the heart is murder in the heart.

Consider reading the full text of the recent brilliant column in the Independent by Howard Jacobson, titled ‘Choking in the stink of our own self-hatred’ about the Islamic terrorists' attack in Bali, but more generally about Jewish and Western self-hatred, and how that allows these kind of atrocities to continue:

‘You see, you read, you breathe in the evidence of an unimaginable crime done to you and yours, and you can't comprehend that such a thing could come, causeless, from nowhere. So you become the cause. There must be reason in the universe, so you become the reason. It's partly altruism: you cannot bear the thought of random being, so you supply the system. In that way you also supply the God.
...Here is our decadence: not the nightclubs, not the beaches and the sex and the drugs, but our incapacity to believe we have been wronged. Our lack of self-worth.’
