I know it's not nice to be piling onto an ailing old man who probably isn't going to be around much longer, but yeah when he was in good health he was an awful person who didn't give a single fuck about anyone else who was having a hard time, and had literally decades filled with opportunities to help people who were worse off and squandered them all just to accumulate more worthless power and money for himself.
Keeping him in power does nothing but harm other people and the country in general IMO, although to be fair that was also true before his health started to go south as well.
I agree it is sad but also when he was well, if he'd seen someone else in the condition he's in now and had the choice to either cure them or make $1 for himself that he didn't even need, I'm 100% convinced he'd have walked away a dollar richer.
