My mom took care of her father for ~2-3 years from when he started getting sick (and tbh a little dementia) to when he passed. It was really tough on her, even with some help. She told me she plans to not put that burden on anyone else, and has prepared for that situation exactly. People change as they go through suffering and some of the nicest people become quite difficult to deal with after years of physical problems, pain, etc. People also have lives and having someone around to deal with medical issues, or even wipe them in the bathroom, or make them a meal etc becomes challenging especially if the person's kids don't have other people around to help. That doesn't make putting someone in a home better, but its not simple like you seem to think it is.
