Even Christianity is based on fear. The fear of 'the Judgement day'.
That just doesn't make sense. If you believe, there's nothing to fear from judgement, because believing in Jesus saving us means we won't be judged for our sins at the judgement, and if you don't believe, well you aren't going to be afraid of something you don't believe in, right?
This is actually a fundamental problem- Christianity takes away responsibility and gives all responsibility to Jesus, which kind of makes all of the ethical codes unnecessary, although Jesus emphasizes the permanence of the old testament law. Just one of many contradictions. You can really see the development of Christian theology if you read church history, although I think the council of Nicea was one of the definitive moments.
It doesn't take away responsibility, because once you're saved and have the Holy Spirit inside of you, you will feel convicted of your sin and want to stop doing it. You will become more Christ-like as you live and follow the commandments.
