All depends on the situation/crime and then the timeline you are looking at for both the player's career and his past transgressions.
For Tyreek, virtually every study available suggests that as long as Tyreek and Espinal are together, there is an increased risk of violence since there have been incidents already. Even if they are not together, they have children, so they will most likely have contact for the rest of his playing days. Considering we value WR's to have a longer FF shelf life than RB, this is a major concern for me and I would never pay up for Hill.
For Hunt, RB's have shorter shelf lives and to be honest, Hunt just looks like a bully that needs to get punched in the mouth. Some anger management classes and staying out of certain environments should remedy his situation. Even if he gets into another bar incident, as long as he doesn't hit a woman it won't be a huge deal. If his hotel antics had been toward a man he would still be on the Chiefs.
Then you have a guy like Preston Williams. Universally regarded as a 1st round talent but went undrafted because of off field concerns. Now you have a guy on IR, living in Miami. Sounds like a recipe for success if you ask me. Considering we have some serious offenders in the league, with violence against others on tape, and they still get drafted early I'm not sure I even want to know the baggage Preston Williams has to go undrafted. Let that sink in.
I look at each player's risk and the likelihood to be a repeat offender before I make a judgement on value. Obviously the price can always get low enough for them to become a buy (similar to PW and most getting him in the 3rd or later before preseason), but I try to be pretty informed and look at the whole situation.
