What does the fortune teller mean when he says there is a bad god?

In eastern mythology, people who are called immortals are basically good people. But in western mythology, God and man are almost the same, and there must be a distinction between good and evil. This good and evil is generally related to what this god cares about. Actually, I think it's God's nature. This is quite rare in our oriental mythology. (However, Japanese mythology should also be different from the oriental mythology I mentioned. When I say oriental mythology, I mean China mythology. )
