The more interesting question to ask an atheist is, "Do you hope you are right about God and the (absence of an) afterlife?"
If you are right then life has no meaning. There is no reason to be "good," kind, charitable, honest, fair, or considerate. No reason to leave a tip in an establishment where you will never go again. No reason not to cheat on your taxes. No reason to tell, for example, the truth to an insurance adjuster. No reason to be faithful to your spouse.
You SHOULD BE a sociopath, concerned only with "will I get caught?" and what are the risks of my selfish behavior?
Atheists respond, "Well, if fear of punishment is your only reason for being good, you are a moral cripple. I don't need any of that to be generous." But the response is in the facts. You [the atheist, statistically speaking] are not generous. Atheists do nothing for their fellow man, nothing to charity, and so on.
Wouldn't it be a better world if EVERYONE believed in God, and believed in a reward for virtue in the afterlife and punishment of evil in the afterlife?
The answer is obvious.
Look all you want at religious fanatics doing foolish and harmful things. Any belief system can be perverted to self-aggrandizing ends. But believers do more good in a day than all the atheists in the world to in their collective lifetimes. China is a good illustration of what happens when nobody believes in anything. They will cheat you blind without giving it a second thought. I could give a dozen examples, headed, of course, by theft of intellectual property, which is a national policy.
