@vriska often addiction is caused by an individual being unable to express some aspect of their personality within their society/environment and a healthy expression of those aspects makes such problems drop away
"once and addict, always an addict" implies such an expression of the personality is not possible and keeps the person under the heel; whether a moral failure at risk of relapse (AA) or a helpless victim of their environment (Liberal politicking) the addict just becomes another alienated pawn.
so much for today's study procrastination and mild fedi addiction, I'm sure the two are correlated.
