And one of those drunk people may turn out to be the next RDJ, which went to become sober and take his most famous roles and now donates millions to FootPrint coalition, Make-a-wish foundation, among others, or maybe Slash from Gun's n roses which almost died from a drug abuse and is now sober and helps many folks with his S.E.R.P.E.N.T. festival; pretty sure a number of EMTs were part of their lives when they were at their lowest, so yeah, making judgments based on where someone is at at any given time is not the best for society or for any given EMT; heck, I would have loved to help Hemingway once despite being an alcoholic until his bitter end, so no, when you look at life the way you describe is almost looks like you are looking for the burn out; I'm more willing to believe in physical burnout in that profession, is well known being an EMT can make quite a number on your limbs and back.
