Depends on your uncles motivation. Is he trying to help the man? Is he extending the right hand of Christian Fellowship? Is he hoping to see a change in this "pill poppers" lifestyle?
It would be a shame to miss out on an opportunity to REALLY help someone through hard times by turning your back on them.
Everyone has tried extending a hand to this guy while he was married to my cuz, but he just doesn't want it. The land is still owned by grand parents but they are so old they really dont know what is going on anymore. So that being said I think I'm just going to confront him and try to explain the situation which I'm sure he is aware of.
And the last reply by BMAN a seem fair. Then if he don't straighten (be a dad to his kid) up vote him out.
