Parents gave birth to us and raised us, so it is natural to repay the kindness of birth, illness and death.

Your uncle didn't give you life or support you. Of course, you have no obligation to support him.

Of course, if you give him a pension out of morality, then we all praise you. Your behavior is great.

But if you don't do it, no one is qualified to judge you. This is your right, the right to choose freely.

Of course, it is natural to support parents under normal circumstances.
