Should my cousin help more at home since he lives rent free with his mom?

i have a cousin who is married and ahve two kids. He never married the mother of his kids but live together for some years before the wife moved to the USA with the kids but still he supports them. Tha is because there were more opportunites for his kids than where they were living. SO the woman took them with her to live in the USA and they had been living there for more than 10 years now. My cousin remain in the same town his kids grew up and now he works for the family like a farm administrator. Let me be clear my family (aunts are not rich in order to have a farm, it was inherited from their dad many many years ago) in fact this farm had caused more problems than benefits as the years went by (money debts plus other stuff but so far it has been impossible to sell the farm cause the farm itself has legal property issues that need to be resolved first before selling). Most of the relatives do not get along well now, as many problems had arised as a result of this eternal farm problem. Anyway. my cousin as a farm administrator since he works for the family to be in charge of the farm (alhtough it seems he is stealing from the family but everyone keeps quiet so to avoid h ard feelings and resentments) he is employed as an administrator for taht he gets a salary and social responsabilities but since the family is nto rich he is owed many years of salary but he is aware the family does not have money to pay him so he says when he is not charging them money. My cousin has a second job at some local hotel. The thing is that my cousin live rent free in the family house he share with his mom, his mom is an elderly woman who for some health issues for her is difficult to walk now. He is rent free, eats free also but he is not helpful, he does not help around the house not to even change a light bulb, he does not keep an eye when workers go to the house to do some house maintenance services, you know just to check the worker does the thing correctly.

I mean he is the man of that house but does not help at all and not even for consideration of his mom who is elder and for her is difficult to keep an eye on things for her condition but then he sleeps in the house and eats in the house.
