As a sister, should I help my brother buy a car?

Didn't say whether this kind of thing should be done. Parents are unable to share the responsibility for their parents in order to be filial to their parents. My sister has the ability to help my brother buy a house and a car and solve his parents' difficulties. In other words, she is filial to her parents and helps her younger brother. Didn't say whether she should help her brother buy a house and a car. She wants to do what she can, and she does have the ability to help her parents. She can't help her brother if she doesn't want to. Just for her brothers and sisters.
