I think a better way to look at it is a pharmaceutical company is full of people that would obey the ignorant orders of a middle manager in a hierarchy with incorrect safety procedures or obey the orders of a small group of evil managers colluding to bypass those procedures without the knowledge of their subordinates.

There's no reason you need more than a handful of people to be deliberately evil. Plenty of people will follow them unknowingly or under the threat of losing their jobs.
