Vaccine to Prevent Killing Human Beings?

jawahar asks: "I wanted to ask Slashdot whether it is possible and desirable to develop a vaccine which, when consumed, prevents a human being from intentionally killing a fellow human being. How much funding is required to develop and distribute such a vaccine?"

Ecstasy does. It's decently cheap, too. Just pump up the whole nation on it, and we won't have any problems with violence. We will have problems with STDs, though.
