[Wisdom will deliver] you from the way of evil, from men of perverted speech, who forsake the paths of uprightness to walk in the ways of darkness...
Proverbs 2:12-13

It sounds like these men are backsliders because they "forsake the paths", but that's not necessarily so. The Hebrew word for forsake can also mean to eschew or reject. In any case, it does mean that they are aware of what is right and have refused to follow it. Stay away from those guys.
