I just meant, that if he has a psychotic break, it would result in a full blown personality swtich and he would adjust his view of reality. Given what it is now, he would ned up facing all these problems and actually working on them.
I appreciate that you think some kind of "psychotic episode" will turn him around. I am not that optimistic. He will go down this road until the end. I refer you to another charismatic, delusional, narcissist who led a powerful western country in the first part of the last century. He just kept doubling down also. It didn't end too well for him, or the citizens of his country.
