Gelty Conscience?
It's about the money, not the principle. What else can it be about when a doctor hides evidence that a drug seems harmful? Duff Wilson writes in The New York Times that AstraZeneca "buried" unfavorable studies of their psychiatric drug Seroquel:

In one of the documents, a 1997 e-mail message, Richard Lawrence, an AstraZeneca official, praised Lisa Arventis, the company's Seroquel project physician at the time, for minimizing adverse findings in a "cursed" study. He wrote: "Lisa has done a great 'smoke-and-mirrors job!' "

Lawyers suing AstraZeneca, a British drug maker whose United States headquarters are in Delaware, said the documents show it tried to hide the diabetes link for nearly a decade.

"AstraZeneca knew about the risk of weight gain and diabetes in 2000 and not only failed to warn physicians and patients but marketed in a way that represented there was no risk," Edward F. Blizzard, a Houston-based lead lawyer on the cases, said in a conference call with reporters.
