The freaky part is that she feels guilty. Why? She can harm anyone she likes without guilt, because there is no punishment when there is no good and no evil.
She can be wantonly cruel, vicious, sadistic and vile. As an atheist the only punishment or even feelings she needs to concern herself with are those of other people, unless she can evade those as well.
If she wants, she can buy infants and bash their brains out on rocks. She can give boxes of poisoned candies to elderly people living in nursing homes.
She is free of God, but also free from morality and ethics. She can live as an animal if she chooses, and remake herself as a monster.
Of course, according to orthodox Christianity, she can do all that s**t for fifty years, then come to Jesus, and everything's cool.
As opposed to any of those old folks she poisoned....if any of them lived a polite, law abiding life for eighty years, but to their dying day remained honest doubters about God, well, they be fryin' for all eternity!
