Or they simply don't believe in your religious mythology. It's not that people "want to sin", is that they have no reason to believe in what you're telling them about your deity or holy book. Why would anyone in good conscience want to serve a god who tortures people in hell for all eternity, keeping them alive to be tormented forever in a fiery lake, because they didn't convert to the right brand of Christianity? Notice, it's not just converting to Christianity, you have to convert to the right type of Christianity to be spared from being tortured. Who in their right mind or with half a brain cell, would believe in such immoral, evil claptrap?
