AITA for refusing to visit my alcoholic mother until she gets sober?

My sister and I grew up with an abusive alcoholic mother. We were barely 10 before we realized we had to parent her back, and take care of ourselves. We weren't showered with love and affection. I'm not even sure if she remembers my birthday, but I do remember her clocking out early and leaving me alone on my birthday so she can get drunk. I felt like I was just something she had to do, while drinking and smoking was more of a priority. Whenever dad came home, she would pretend to be the perfect mother but he never noticed our pleas for help and believed that she was as good of a mother as she was to us when we were babies.<br><br>It got so bad to the point where she would have these "accidents" that we had to bale her out of. For example, one time she passed out with a lit cigarette in her hand. Thank god I was home that day and saved both her and the house. <br><br>After going away for college, I only came home now and then because I didn't want my niece and nephew to be traumatized by their grandma who would often urinate on herself and say weird stuff and scare them. My sister moved them away so they won't have to see her like that. My dad was diagnosed with pancreatic cancer and was told he only had 6 months to live. He passed away, surrounded by his daughters and grandchildren. He cried about leaving them behind.<br><br>The problem arose at the funeral when my sister and I expressed that we wouldn't be visiting her at home and we wouldn't want the kids to visit either. It caused an argument and my sister and I are being blamed for not taking responsibility for our mother and being "evil daughters" for not giving her a "second chance" to be a better mom. We've given her thousands of chances and second chances and she has never used them. AITA for not wanting my kids to be around a toxic woman who is a hazard?
