People orchestrate their own fate, largely.
It’s not society’s responsibility to “save” someone. If help is required, then great. Here. If you abuse help by taking it with less than sincere intent or fuck up again and again, you’re on your own.
Drug addiction is weakness. Disease my ass.
Everyone screws up, to lesser or greater degrees. Me. You. Everyone. However, folks who are determined to meet destruction need to be given freedom to achieve just that.
Fuck-ups with very few exceptions become lifelong fuckups, harming everyone and everything with which they come into contact.
This guy would seem to be a fuck-up.
Let him meet his fate.
