Are you planning to put your parents in a nursing home?
I refuse to. I've been in some "nice" ones and I've been in some "bad" ones. Abuse happens in all of them. Don't be daft and think it doesn't or can't.
***Yes,I realize that some people have "no other choice" than to put their parents in a home.I'm not directing this at you.***
However, most do it because they can't work taking care of their elderly parents into their busy family schedules. It's a good thing your parents didn't feel the same way about you when YOU were helpless and dependent on them.
If your parents were assholes...then do what you want. But if your parents loved you and did their best for you...why would you put them through this?
