People who use confession as a get-out-of-jail-free card

I'm an atheist, so I don't see confession as much more than a way for people to ease their conscience about bad things they've done. But let's just say, for the sake of argument, that there is a higher being hearing confessions and forgiving sins. There is still a glaring problem I see with the way some people use it. I would think that a large part of receiving forgiveness would be a genuine realization that what you've done is bad (not "I'm confessing because I know there's a rule against what I've done", but rather "I'm confessing because I feel bad for doing this thing"), and a real desire on the part of the confessor to avoid doing that thing again. But some people don't really feel all that bad about what they've done, and know very well that they are going to continue doing it. An example: I read an interview with a porn star once in which she talked about how she was a devout Catholic. She said that she knew God forgave her because she confessed every Sunday. But if that confession is made with full knowledge that she has no plans to change her behavior, why would God be forgiving?

Likeswise, over the years I've read articles where they'll talk to people involved in narco trafficking, and again, people are like, "Sure, I behead people who stand in the way of me pushing my drugs...but I always tell God I'm sorry, so I'm pretty sure I'll go to heaven."
