I'm not trying to shame people who don't read The Classics because god knows most of that stuff never saw an editor, but before you post/reblog quotes from the old book classics, framed as something the author personally said, you should be aware that the quote was probably said or thought by a character who wasn't supposed to be objectively correct. As a matter of fact a lot of those fictional little guys were written to be completely wrong on purpose.
You have heard of the sci-fi genre of Don't Create The Torment Nexus. Now consider the 1800s book style Don't Become The Dipshit Protagonist.
It is actually way better for 100 addicts to get their fix on pain pills than a single person in pain go without. I call this the "Torture is bad" principle. You should be able to get the good stuff forever after a single doctor's visit. If you're worried about addicts fund rehab centers and needle exchanges instead of torturing people.
