Yes, it does, see above.
dw; Arguing that I can't prove that my morality is the one true moral system does not establish or provide that morality comes from god. You are only demonstrating that you think the moral system based on god is best and that you don't know how to have morality without the god... and that makes you a sociopath, not me.
No, you as an atheist and all humans have a built in moral conscience because you are created in the image of God. But over time it becomes distorted due to our sinful nature which we inherited after the Fall of humanity. There are few sociopaths, people born without a conscience or they have ignored their conscience to the point where it is destroyed.
dw: You saying that you can't imagine morality existing without god is your problem, I know I have a moral system, I don't need to prove that it's best and it will never depend on your god.
You have moral feelings based on your conscience but if there is no God then you don't have an objective moral standard to make objective or real moral judgements. It is just based on the feelings or chemicals in your brain just like Stalin, so how do know that your morality is better than his?
