This is an interesting article on how the existence of free will (or lack thereof) affects our moral actions. I'm wondering, if free will doesn't exist, should we hold individuals and ourselves responsible for their actions?
"Many philosophers and scientists reject free will and, while there has been no systematic study of the matter, there’s currently little reason to think that the philosophers and scientists who reject free will are generally less morally upright than those who believe in it. But this raises yet another puzzling question about the belief in free will. People who explicitly deny free will often continue to hold themselves responsible for their actions and feel guilty for doing wrong. Have such people managed to accommodate the rest of their attitudes to their rejection of free will? Have they adjusted their notion of guilt and responsibility so that it really doesn’t depend on the existence of free will? Or is it that when they are in the thick of things, trying to decide what to do, trying to do the right thing, they just fall back into the belief that they do have free will after all?"
