I would suggest staying well clear of your "friend", partner, whatever. "Deacon" implies you are trying to correct certain social behaviors. Are you familiar with "Old Testament retribution", your house, your family, your livestock?

The behavior you describe will eventually catch up to him, and it would be best if he did not think you were a part of it. Do not approach, do not intervene.

If he is showing any defective behavior on the job, his co-workers have several methods and procedures to deal with it and they certainly will, let them handle it.

Your odds of getting shot in a domestic dispute are fairly high.
