I (25TF) recently had a falling out with my sister (28F) bc she told me it was "pathetic" to help others bc it "didn't help herself."

I was seen giving money and food to a homeless person, and she told me I was endangering myself. She said that "homeless people have guns and might stab you" and that I didn't have the right to help people.

She has had a history of blaming everything on me while she listened to her father beat me, when asked why she did that, she said it was bc I'm trans and shouldn't be allowed to exist.

She tries to destroy every single friendship I have and even goes as far as to tell me I don't deserve to be loved and that I should be locked in prison for my gender identity.

She repeatedly gaslighted and manipulated those around me into thinking she's right, and that people should believe everything she says about me, even when it actively harms me.

Now she wants me to apologize for blocking her, deleting her number, and marking her as spam a year ago. Should I manually add her number back in and give her a second chance, or should I cut her out of my life forever?
