Sin is a religious concept that does not exist for the non-religious who would probably define religious sin in the context of moral (or immoral) or ethical (or unethical) behavior.

You are greatly mistaken in your opinion that sin is an idea only. One day, unless you first change your mind, you will encounter a Non-negotiable Rock that will prove how great and far-reaching your error.

Show me where I said that the concept sin did not exist for me personally.

A non-religious -—atheist for example— will define what Christians call sin in secular terms such as moral and immoral behavior, hence their belief that humans are constrained from acting badly by the need for an ordered society. I am not saying I am arguing this, only explaining why the notion of sin and disordered are different things in my mind.
