But for the most part, people know that even though their dad may have molested them and their sister and all the neighbors, that even though they are angry and bitter and afraid in a way that effects them every day of their life, they know that the law says they cannot kill this person. If they decide that their anger and/or the anger of others justifies breaking this law, they are still making a decision, making a choice.
Humans are conscious of their thought processes, and I think that if more people took the time to understand themselves and why they feel or think some of the things they do, they would realize how much choice they really do have. Genetics and upbringing can influence you, very strongly in some ways, but I believe that if you make yourself aware of these factors, make yourself aware of the influences acting on your choices, then you can make better decisions. It's part of taking responsibility for yourself, which is something we have to do in a civilized society. You can't just let your anger run amok and go killing people when it takes your fancy. That's why the law charges you if you fail to be responsible for yourself in this way.
This is partly why I'm interested in studying the evolution of behavior. I completely agree that there are genetic influences acting strongly to drive us toward certain behaviors. But when we're aware of these influences, we can understand that perhaps the suggestions they're making don't have a place in a civilized world. It's like a guiding compass for when we're trying to decide if that "gut feeling" is right or not. That feeling may be hundreds of thousands of years of evolutionary history driving you towards a certain goal that used to result in increased reproduction, but that may not apply in today's world. Similar thinking can be applied to the influences of experience - knowing what you went through and why it effects you the way it does. I think we're lucky in that few if any other animals are capable of having this kind of perspective on themselves.
