Is it wrong that I don’t want to buy Christmas gifts for niece and nephew or sibling?

I don’t have a relationship with my old sister and she’s been nasty to me over the years. I don’t care to be around her and I have no interest in her children. She’s also never given me a gift for my birthday or Christmas. I don’t want to give her or her kids anything for Christmas. It brings me no joy at all. I rather give to the homeless.
