Can you sell a soul to the devil for a wish?

Some people believe you can, but this happens to be a very old myth. There is actually no evidence that the bad choices we make in our lives are caused by devils or demons-- they are caused by our own foolish decisions, and if we do wrong, we have to accept the consequences of our actions, and learn our mistakes. Some Christians do believe there is a devil who tempts people and causes them to do bad things, but not all Christians share that view. Most people understand that we have free will and can choose whether to do good or to do evil.
