I care, just different per family member.
My mother, Despite bringing me into this world she was a horrible human being, drug addict, abusive, hurt everyone in the family one way or another, literally killed one of my siblings because she could get away with it. I care, I care in the sense that I make sure she doesn't get peace from it ever again, she will never have a good life, I will purposefully hinder her progress, anytime she makes a buck, ill make sure to let her employers know what she did and still does, every family member knows to stay clear of her. By proxy they associate a lot of the bad with her children as well, so I am not liked in a lot of the family, as I'm viewed as devilspawn, kids that shouldnt have been birthed, a liability to the family, so yes, I care, care to hate her.
My father is a good and honest man, I do not keep in touch as he got himself a new family, new wife, new kids, he tries to put his past behind him with his former horrible woman, and as a result doesn't keep in touch with me, nor do I want to pry into his business, but once a red moon we'd write each other to see how life has progressed, he is proud of me forging my own path away from the witch, and I am proud of him for doing so as well, we care in that sense.
Everyone has different walks of life, and if your mother genuinely cared about you, you should put a little care in her. It may not feel like it now, but as the years go by you will realize you were born, raised and cared for, and will feel the need to care for her in her slow passing from this world. And if you don't then you do not deserve any of these words.
