Every human has emotion, even if we do not like to admit it sometimes. I think it's just natural for us to feel... as science would explain it's all chemical! I don't believe that, I find it interesting even in the spirit realm... People that have died, still hold true to what they feel and believed in life. When it comes to murder, we do not have to go by a book, or a belief ( some do ) it comes from inside... If we know we are killing life, something so precious... we think about all the people who will mourn this person after they are gone. Even in acts of violent murders, the person can regret it later; rage often blocks logical thinking. If it hurts someone else, then I believe it is wrong. Thats what the police/government is there for, to keep things in order for those with little morals.
