Many such people say that the problem of evil is the main obstacle preventing them from embracing theism. Such people will also be deeply interested in responses to the problem of evil. The problem of evil is only a problem in the broad context of theistic reli gion. People who deny that God is omnipotent also find answering the question eas ier. Evil exists, they can say, because God does not have the power to prevent the existence of evil.
Theists can take neither route.
Accordingly, the question of evil is much harder for them to answer. And if God is perfectly good, God must be willing to prevent evil. Then he is impotent. Then he is malevolent. But even this argument is still a bit vague.
