There are plenty of moral and immoral atheists just as there are plenty of moral and immoral christians.
What makes someone a moral person has nothing to do with their religion or lack thereof. It has to do with how they treat people and the daily choices they make.
You can cite anecdotal evidence all you want, but fundamentally, the atheist has no objective basis for morality. Like Richard Dawkins says, there is no good or evil, just DNA replicating across the universe.
He explains how a female digger wasp lays eggs inside a caterpillar so that her larvae can eat it. She paralyzes the caterpillar but does not kill it so that the body remains fresh. Dawkins speculates that if the wasp’s venom included an anesthetic, then the caterpillar would not suffer while being eaten, but “nature is not cruel, only piteously indifferent. This is one of the hardest lessons for humans to learn. We cannot admit that things might be neither good nor evil, neither cruel nor kind, but simply callous—indifferent to all suffering, lacking all purpose.”[SUP]9
[/SUP]Dawkins returns to his example of the wasp and caterpillar and says that “Nature is neither kind nor unkind. She is neither against suffering nor for it. Nature is not interested one way or the other in suffering, unless it affects the survival of DNA.”[SUP]13[/SUP] He describes the crash of a school bus and quotes a writer who argues that the horror of such tragedies confirms that we live in a world of values, because if the world were just electrons, then there would be no problem of evil. Dawkins responds:
On the contrary, if the universe were just electrons and selfish genes, meaningless tragedies like the crashing of this bus are exactly what we should expect, along with equally meaningless good fortune. Such a universe would be neither evil nor good in intention. It would manifest no intentions of any kind. In a universe of blind physical forces and genetic replication, some people are going to get hurt, other people are going to get lucky, and you won’t find any rhyme or reason in it, nor any justice. The universe we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil and no good, nothing but blind, pitiless indifference.
