Here are some plot details.

Its about a bunch of kids, something happens and they shot a guy maybe two over something (maybe a car)and they bury them out in the woods (I remember one of the kids say "he looks scared" as one of them dies )and a the years pass and then later talk about it as adult, one of them is a priest and when he is smoking one of the other characters ask "isn`t smoking a sin?" or something along those lies..

Any idea which film this is?

Is Kevin Beacon in it. Sounds familier, maybe search his movies.

Sleepers

That's not sleepers

That is what I was thinking.

How old is the movie?

This doesn't remotely sound like Sleepers.
