Unbelievers are superstitious and unrepentant, what they want is :"I am my own God, I can sin and escape punishment".
Sounds like you've got some baggage there.
Superstition is believing stuff for which there is no proof. Usually it goes along with a healthy dose of "tradition". Sounds a bit like religion, don't you think?
Regarding repentance: a moral person should repent when he or she has done something morally wrong. Your post suggests that you think that failing to believe in your preferred god is a moral wrong, for which "unbelievers" should repent. Is that what you think? If so, can you explain why it is morally wrong for somebody not to believe in your god?
Regarding being one's own God: I'm not sure what you mean by that. Do you think that everybody needs a figure of some kind to worship, and that "unbelievers" worship themselves? Or do you have a problem because unbelievers think that when it comes to moral responsibility the buck stops with them and not with an invisible man in the sky?
Regarding sin and punishment, you are claiming that unbelievers
want to "sin" and "escape punishment". Let's unpack that a little.
First, the concept of "sin" is a strange concept. A "sin" is like a wrong done to God, isn't it? Take littering, for example. A person who throws litter on the ground commits a sin. Why? Because God doesn't like people making a mess, and God gets offended. Or something like that. Am I getting the idea of "sin" right here? And since the evil litterer deserves punishment and yet gets away with it in this life, then God will exact punishment in the afterlife, or something. And it follows that the unbelieving litterer is hoping to escape God's righteous justice by failing to acknowledge that God exists. Is that how it works?
Let's leave that aside, and mention a couple of other problems. The second one is this idea of "wanting" to act immorally. Why would an unbeliever be any more prone to that that a believer? Or, if you want to investigate the matter, is there any evidence that, in the real world, unbelievers do wrong more often than believers? And we might also ask: does being a believer make somebody less likely to want to sin?
Third problem: if the believer is abstaining from sin because he fears God's punishment, rather than because it is the right thing to do, is that good? What if we take away the threat of God's punishment, and just act morally because that's what it means to be a good person? That is, be good for the sake of living a good life, rather than because you fear punishment in the afterlife. Could that possibly work as a life philosophy, do you think?
