He will trap you again like anything
If you are not sure whether God exists or does not exist than why you believe in a religion or religious elders ? What are you compelled to obey or follow your religious elders ? The Story of Religions or Religious elder's starts after existence of GOD not before that.
If One is undecided about God than He has no ground to say that I don't do xyz acts due to my religious elders.
A person can Sin even while remaining in a faith. He can hide his sins from others. Even if he leaves his faith he can hide this aswell. To say that people leave faith so that they can indulge in sins is a statement for which the evidence has to be presented by the one who made this claim. The Onus isn't on the other person to give evidence that this isn't the case because He did not claim it.
