My brother
-is 37
-has never had a job in his life
-has been a meth user on and off for at least 18 years
-has retinitis pigmentosa and is now legally, but not totally blind
-has a long rap sheet for crimes including harrassment, assault, theft, DUI, driving with a suspended license, probation violation, though I don't think he's been arrested since about 2015 or so.
-is extremely irrational, possibly psychotic, and has a horrible character.
This happened because my father is quite simply the biggest enabler of all time. My brother's lifestyle revolves around abusing and manipulating my dad to make him do what he wants, and my father's life revolves around enabling. My father still doesn't understand the concept of enabling after 20 years of people explaining it to him.
I've totally given up on my father, whose 67 year old mind is so broken that he can never see his mistake. For many years I tried desperately to get him to understand that he was harming my brother, but it was futile. Lately it occurred to me that I should have focused my efforts on my brother instead. I do not know if it would have worked, but the chance of success would have been higher than working on my father. I did not help my brother during those years because I was more focused on my hatred of him, as he was abusive toward me.
At 37, with his background, blindness, and destroyed mind, it seems his life is ruined irretrievably. In a year or two my dad will die and leave him a few hundred thousand dollars, and that will be what he has to live off of the rest of his life. As bleak as his future is, the more rational he is, the better off he will be. Is there anything I can do at this point to try to help him lead a better life, or am I better off cutting all ties?
