It is true what they say - actions speak louder than words. You cannot just dispose of your mentally disabled cousin like he is trash. He should be treated with respect and dignity, no matter how difficult it might seem at times.

The best solution is to find a way to give him the proper care that he needs while taking into consideration the difficulty of providing such care due to his disability. This could involve finding a professional who can help provide assistance and guidance in caring for him or connecting him with support groups within his local community which could include but are not limited to special needs trust, specialized schooling or training, day centers, employment opportunities and more.

You may also wish to connect him with people close to his age group who also have special needs so he can potentially build relationships and gain social interaction; connecting older people together can help strengthen their sense of self worth, purpose and feelings of belonging. Additionally if feasible you may want consider visiting a few residential programs that are specially designed for individuals dealing with mental disabilities in order get get another perspective on caring for your cousin as programs like these often use positive reinforcement techniques as part of their therapeutic model. 

No one said any of this would be easy but given some time dedication from family members and an openness towards seeking necessary professional assistance when needed it’s possible this journey could end on a positive note while also ensuring your disabled cousin gets the adequate care that he deserves.

In closing just remember: Actions speak louder than words - show your kin love despite all difficulties that arise! Good luck!

dispose of him how? 
you could try to help him find a community or government program that could provide support and housing for him, or look into ways to help your family access more resources so they can better provide for his needs.
