For context: I had an uncle who was an alcoholic/addict, with his addiction being the result of immense trauma he suffered as a kid. He was fired from his job in the medical field after writing himself scripts, and made a genuine effort to turn his life around. He went to AA and other therapy, brought his sponsor/buddy to events where there would be alcohol, and generally took it seriously and worked to improve.
A few years later, we got a call in the early morning. He had overdosed and died after an argument with my aunt. It's unclear whether it was a relapse or if the overdose was intentional, and to be honest it didn't matter. My aunt was distraught, he was dead, and their kids now had no father. It was a horrific tragedy.
When I got up to ask what the phone call was for, my mother had a huge smile on her face. She thought his addiction was a moral failing that automatically made him a bad person, but she also judged him badly for needing AA and the buddy syatem to stay on track. She told us, with glee in her voice, that he had "finally killed himself".
It took everything in my power to not lay into her, which I didn't do only because I knew she would never change her mind. It was just the latest and worst example of her horrid behavior. I never told my aunt, but I did tell other members of my extended family when they asked why I didn't talk to them anymore.
