I don't think many addicts give up drugs because they're upset by the human cost and implications to other people!! hmm - right, and what does that make them? 
You know what - I think he's on a winner here. I think we should all just sit back, jack up, get someone else to pay for that. Why the fuck do I drag myself out of bed at 630, out into all weathers to sit behind a desk for 6 hours, to make money that I spend on food, clothes, mortgage...
Why shouldn't we all sit at home, get someone else to bring me second-hand clothes, food, send me money, phone me to make sure I've got enough money and substitute drugs, take me on holiday, have sex, basically look after me?
Why do I lie awake worrying about paying the mortgage, making sure other people are clothed and fed and clean and healthy - Why not get OP or someone like her to do it all for me? i could cite a neglectful childhood, or unspoken verbal abuse,
or whatever else I can blame,is stopping me from actually living a decent life and putting in to society rather than taking - and living the life of Reilly, laughing all the while. What a Life!!!! 
Except, of course, if we all did that, there'd be no money, no methadone, no-one to bring you food or clothing or drive you on holiday or have sex; we'd all be waiting for someone else to do it for us.
It's the absolute epitome of selfish and self-absorbed and it is hugely unattractive (to most people, but not apparently to you) and yes, maybe he should be thinking of the human cost.
As should you, if you are with him and seemingly strangely proud of him, and therefore condoning the murder and torture of children yourself.
