I don't want to allow sister to see or speak to my daughter.
That seems cold. What is the reason for keeping your sister away from your daughter?
I want her to ruin my relationship with my daughter
Even if you have a poor relationship with your sister, it isn't right for you to prevent your daughter from seeing or speaking with her. Your sister is family and it's rude and inappropriate to cut off family members from interacting with each other. You should allow your sister to have a relationship with your daughter if she chooses and also attempt to repair whatever rift has formed between you and her.
She's not family anymore. I don't want her in my daughter's life anymore.
Even as a parent you shouldn't be prohibiting who your daughter can see. Your sister is still her family and depriving her of that relationship can be painful.
