Should my sister be my maid of honor?

I’ve recently got engaged and I’m trying to figure out my wedding party! My older sister and I use to be close but we no longer are. We share many different viewpoints on pretty much everything, including my career, my choices, etc. Since meeting her husband, she has changed drastically and she is incredibly hateful, hurtful, and just plain rude now. I’ve pretty much cut off contact with her due to the issues she has caused mentally for me. When we were younger, we always said we’d be each other’s moh’s, and I was her moh in her wedding 5 years ago. Now that I’m getting married, I need to decide if I should honor what we said, even though I haven’t spoken to my sister in months, or if I should choose someone else. If I don’t make her my moh, I believe that she was cause drama and chaos on my wedding day. Help!
