I will have to sound different way on this matter because is a family we are talking about and in family they lookout for each other's regardless of how things could be for another, but on this cases from what you said is actually somehow because if somebody is doing the right thing there is no how everybody will turn against you, there must be someone to defend his interest. However if truly he has been badly treated as he said when has done nothing bad against them, then he should use it as a challenge to lookout for himself alone there will come when those people will call for his assistance.
