And if you want more evidence than that, then I suggest reading about Stanley Milgram’s famous experiments. A little quote:
Moreover, even when the destructive effects of their work become
patently clear, and they are asked to carry out actions
incompatible with fundamental standards of morality, relatively
few people have the resources needed to resist authority.
I think that if you want yet more evidence then you can probably acquire it yourself. Personally I must sleep.
