It a strong challenge for him but surely he is not alone. Such stupid blames from some lazy relatives are very devastating and occur commonly in most of our African families. The more you try to help people the more they misuse your aid and turn against you blaming as if someone is supposed to work for them. What I normally do when faced with such difficult challenges is to ignore everybody and what they say except my parents. Yes let them be my foe since they want it so. For my parents I only ignore what they say and continue doing whatever I can to help them out of any difficult life challenges. Of course even for my parents, it depends more on my own reach, as human I know I can't solve even all of my own problems. The key to these most difficult family issues is therefore to ignore nonsense blames from those lazy people and then try to find a somewhat convenient balance relationship with your parents and other people outside your own family who are good to you. It doesn't matter much to force relationship with people whose main thing they can do is to blame others for their failures. Even if they are my blood brothers or sisters I just let them behind to avoid unnecessary distresses. Life is too short to waste time minding stupid noises from fake siblings' complaints.
