Doctors and pharmaceutical companies are the most evil people in this country.
Sorry, I don't buy this, especially about doctors. While there are doctors that are evil and do nothing but push pills, I believe there are more doctors who actually care for their patients and try to cure their patients rather than push pills.
As for pharmaceutical companies -- I'm not sure you can assign motives to corporations as a whole. There are pharmaceutical executives that I'm sure are evil, though as a whole I don't think we can indict the entire industry on the basis of some of the executives.
As for trying to maximize profits (not sure if that was what you were calling evil but it seems to be a commonly used reason), I don't see how they are different than most other corporations. Personally, Microsoft seems to be the most "evil" when it comes to maximizing profits -- they appear to sell their products at a price many times the production and research costs, instead seemingly relying on the highest price the market will bear. It is interesting to me that Microsoft has made more millionaires than any other company, while at the same time making the founder the richest person in the United States. Yet I don't often hear people calling Microsoft evil for maximizing profits to a far greater extent than pharmaceutical companies.
Though, for my money, I think insurance companies have to be the most evil; you pay premiums for years and then they try to find a loophole to keep from paying out when you have a claim.
Doctors have become nothing more than pill pushers and the drug companies are nothing more than drug manufactuers.
As for doctors, I touched on that above. And I have to agree with LightHorseman, the drug company comment is

.
The only thing that seperates Merck from Carlos Escobar is that Merck is doing something that is legal under United States law.
While on an emotional level I might want to somewhat agree, the truth is it is hard to legitimately compare the two. First, I have yet to see a pamphlet put out by the Escobar (or any other) cartel listing the proper dosages, known side effects, and chemical interactions of their drugs -- while it is always supplied by the drug manufacturers (to the point that most of us ignore them). And, two, I have yet to see a drug cartel like Escobar be sued for the ill effects caused by their drugs, much less ever seen one of the cartels pay a settlement.
And then it even gets better because when these companies do mess up they simply try and get tort reform passed so they aren't held legally accountable.
And this could be it's own thread here in E&M; though not limited to drug companies, seems like pretty much every corporation is wanting tort reform so they don't have to be held accountable.
