I think this is a harsh and insensitive response to anyone who struggles with addiction or mental health. Addiction is a disease that many battle with all their might, but the disease always finds it way back into their life not due to lack of effort. I’m sure addicts are well aware of the repercussions.
Hopefully some day you will find compassion instead of looking at this as something that is black and white. Every person is different and I’m sorry you look upon these people in need as “placating, enabling and grieving losers”. How about remembering that he was someone’s brother, son, father, uncle, friend, partner, etc. Don’t be so quick to dismiss human life.
