She is selfish by choosing to not "pull her weight". She became selfish by that choice.
I understand there are some communities that choose things like keeping their child deaf, but if you're choosing to put more weight on me then that does go into my perception of you.
I'm not going to force anyone into "becoming healed". But they are choosing. That choice is when it becomes selfish.
No, it isn't as selfish as a billionaire putting children in mines to see their bank account grow.
Everyone makes selfish choices all the time.
Just because you made a selfish choice doesn't make you a bad person, or even means you "hurt" someone. Doing good deeds before doesn't make future acts not selfish.
When I first read "she has all the arms and feet she could ever want" all I did is put myself into the shoes of someone who is helping her. "Oh, all I am is a foot?" Is an easy thing to see someone feeling, especially after learning they're choosing to keep you there.
