Why I believe sin is a choice.
Duh, of course sin is a choice, a decision we choose to do.
Having sex outside of a marriage takes people to meet, have a place to be alone, remove their clothing, do the deed. That is a lot of moments where you are thinking "this is wrong." But every warning you keep ignoring. And then when the sins have all been committed, that's when the guilt pours in. Which means, you know what you did was wrong the entire process of it. You just CHOSE to keep sinning for the self pleasure. And that is where all sins begin at, at self. So whether it's for pleasure, profit, benefit, SELF CHOOSES sin in every instance we commit a sin.
