If the only reason for you to do good deeds are because of a fear of God/the devil, or a need to please God/the church. Then you are not a good person.
That's not fair. Most of them just have no self control, by whatever combination of genetics/upbringing/lack of willpower. When left alone, they go for immediate gratification and repeatedly make bad choices. When they have some arbitrary external system of control, like a fundamentalist religion, they're able to make positive choices. It allows them to be good. Call them stupid, maybe, but they're no more intrinsically good or bad than anyone else. They're just people.
Where they go wrong obviously is assuming that because liberalism doesn't work for them it can't work for anyone, and that no one can make positive choices unless they follow their religion. Trying to restrict other people's freedoms is bad. But someone recognizing that he's making a mess of his life and that forcing himself to live up to the rules of a religion would help him be a better person? I find that pretty commendable, provided he doesn't force his religious views on the rest of us.
