Atheists are immoral
Many theists believe that atheists are immoral.
"The fool hath said in his heart, There is no God. They are corrupt, they have done abominable works, there is none that doeth good."
"The logical result of atheism, a result we have seen right in front of our eyes in one of the world’s oldest and proudest nations, is severe moral decay."
- — Sarah Palin 
- "This, therefore, is the fundamental difference between converted Christians and atheists. Christians have a conscience that is continually instructed, nurtured and strengthened by the Scriptures and prayer, atheists do not. "
- "It is also essential to reject as having any hold over us anything or anyone who asserts that a good can be achieved without it being instrumental to the purpose to existence. i.e. without it being for the sake of Allah. "
"[Atheists] know perfectly well that if everybody didn't believe in God, the comfortable lives they live, in extremely agreeable suburbs, where they can trust people will not cheat them and rob them and mug them and rape them, could come to an end."
- "Another thing is why in the world would an atheist be moral? I understand there can be moral atheists and I do have a few atheist friends that I'm trying to work on. But why in the world would you be a moral atheist? You see, there is no point in it. If you don't believe in life after death is a thing, then as long as you are not going to jail, there is no point in being a moral atheist."
Perception vs. reality
It is important to distinguish between the general perception of atheists, which is often negative, and the actual behavior of atheists, which is usually at least as good as theists.
Americans generally have a poor view of atheists. A study of Americans, including theists and atheists, found that they judged various immoral acts to be representative of atheists but not of other social and religious groups. 
- "Atheists, including those who brought us the Enlightenment, have often been a beneficial force in the history of human thought and religion. They have forced societies to examine empty religious platitudes and hollow religious concepts. They have courageously challenged the moral hypocrisy of religious institutions. The humanistic values of the Enlightenment were a response to the abuses by organized religion, including the attempt by religious authorities to stifle intellectual and scientific freedom."
A study found that fictional evil-doers were assumed to be atheist an almost all countries, particularly ones with a higher religiosity.
The claim that atheists are incapable of any moral actions is absurd in light of evidence to the contrary. In studies that compare overall behavior of different religious groups, atheists often are shown to be more responsible, ethical and law abiding.  Other evidence suggests that morality is very similar between theists of different religions and even non-theists. 
"Which is more dangerous: fanaticism or atheism? Fanaticism is certainly a thousand times more deadly; for atheism inspires no bloody passion whereas fanaticism does; atheism is opposed to crime and fanaticism causes crimes to be committed."
- — Voltaire
Apologists sometimes claim that atheists have a flawed moral system or that morality depends on religion. However, the latter is a separate issue because this does not necessarily imply that atheists are morally worse than believers. For instance, Christians supposedly know not to commit murder but the murder rate is lower in non-religious countries. 
The claim "Christians have their conscience continuously nurtured and structured by the bible, but atheists do not" suffers from flaws, like omitting the existence of all non-christian theists with vastly differing dogmas (one can just as validly claim that this different religion reinforces morality), and not clarifying how a fundamentalist theist's conscience is not always "growing" with their scriptures' teachings, but is constrained within texts (which often reflect by today's standards narrow-minded and bigoted opinions of ancient tribes) demanding blind obedience and not allowing one to question their validity or morality (forming an evolving conscience with reason and empathy is not the same as doing what a single source orders without giving it a thought).
