You spoke of how people often start drugs out of desperation to get away from a bad situation.. ever thought that perhaps dealers start out that way too? For the most part they're just people wanting to make money off what they got, I'm not disputing that, but then again most drug users take it recreationally as opposed to out of addiction so the choice is there too.
On both sides of it there is a massive majority who do it out of their own free will and wishes, and a small number who are pushed there by circumstances out of their own control, but this number is not significant enough to say that all dealers are inherently bad people.
