edit:
I also want to point out that a murder-happy pill is a straw man argument. It will never happen for two reasons: 1-we have evolved to find murder repugnant, so the rewards wouldn't seem appealing to us 2-there are real life repercussions to murdering someone, so the joys would be limited in their duration.
We already have happy medicines that are legal. Valium, alcohol, WoW... I would bet that most people who are reading this have self-medicated on at least one of those before. And those are rather weak medications. They pale in comparison to what the robot was able to do by short circuiting the pleasure center in his brain.
