I can do that, but I am going to address this. I doubt it will change your mind but maybe someone reading can get some perspective.
You need to understand that the overwhelming majority of people who are addicts, booze drugs or otherwise, are wired long before they ever encounter the substance or behaviour. Addiction has been directly linked to historical and childhood trauma - if you need you can look into Dr. Gabor Mate's work on this. He is regarded as the world's leading physician on addiction, and just happens to be Canadian as well. The pathology is linked far before someone encounters a substance and is strongly influenced by environmental factors, especially as impressionable ages. This is the case for most addicts, not all, but most. I have met hundreds and hundreds of people in recovery programs and this is uniformly across the board. And just to confuse you even more, the substance or behaviour (ie: gambling or other process addictions) has nothing to do with the addiction. Thats why the irony of programs like AA is that is has nothing to do with alcohol recovery. It is because the essence of addiction has nothing to do what you take or when you take it, it has to do with how it has manifested in ones life and why they take it.
So did he know the consequences? Probably so. Was he powerless against the addiction and doomed to repeat it again and again and again? 100% he was with out proper supports and a solid recovery program. Every single person I know in recovery came to a point where they did not want to use or drink, but they did anyway. I woke up some days dead set on not drinking that day but would wind up, every single time, drinking. It is powerful beyond measure and there are no sufficient mental faculties to take it on by yourself. It is irrelevant on your gender, creed, ethnicity, profession, religion, or income - if you have some serious underlying trauma(s) that predispose you to be a significant risk, the you might be in a heap of trouble.
This is one of the most misunderstood diseases out there and the stigma out there is really bad. Because to a person, every person I know in recovery would loved to have had the choice to say no. It is far more complex that people think and it is not as simple as not taking a drug or a drink. The roots are much, much deeper and the current research supports that.
So you may say f*** this guy and put me on ignore, and that is fine. But I am going to continue to do what I usual do and that is to challenge the mainstream narrative and address misconceptions. And provided someone isn't a total ignorant asshole, I will gladly partake in a discussion.
