I'm much the same person as I have always been. I love my wife and my family. I'm more compassionate and tolerant of others than before. For example I longer dispise homosexuals. Morality is not lost in Atheism.
Morality is a development of societies.
It's something that comes from within us. The very idea that Christians can proclaim God as moral means that we have the ability to judge morality for ourselves and it does not put God above our judgment. I am much happier today as an Atheist than I ever was as a Christian. Not that I was a depressed Christian. I just don't have to worry any more about hell or have false hope of a heaven.
