My guess is this person is either Southern Baptist, a Christian Fundamentalist, or worse, a Christian Fanatic. Not everyone even believes in the Judeo-Christian God or the so-called Devil. I am a pagan myself, so I believe in a goddess and a god. In any case, if you really look at the Devil as an archetype, it becomes clear that people use this to escape self-responsibility, saying the Devil made me do it. I believe that gambling is ok if you are responsible with it. I also believe in taking responsibility for your own actions.
