It's a distinct possibility. What's more likely is that this person is an example of someone robbed of their own agency, either intentionally or not.

It leads to becoming dependent on others, a true Last Man in the original sense. That's where the resentment starts on the part of the giver, especially when enabling people such as this repeatedly and on long enough timescales.

What's become clear to me is that there isn't anything inherently wrong (morally speaking) with these people, but they need to be moved out of the way so to speak. They cannot be allowed to escape their various containment zones, and the mechanism for their containment must be strengthened.
