If you come to know that ur child has a defect and u can get a abortion done, what would you do?

I will give up the child. I have been through these with my mother for my elder brother. I witnessed how suffering my elder brother was when he was still alive, having fits out of sudden few times a month. He was unable to feed himself, take care of himself, go toilet himself. Also, my mother has gone through a very tough time in taking care of him. Also, as the sibling, I feel a lot of stresses and feel helpless as don't know how to help him. Thus, I feel if I know the child has defect I will not be selfish to keep him/her as the lifetime commitment for him/her, myself, and my family is huge. However, if the defect is not brain damage or serious illness, I will keep the baby.
