Nah. Plenty know that they're doing what they want at the expense of other people. But the bullies who think they're doing something good are the most dangerous, since they don't have any moral qualms about how far they take things.
“Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.”
Everybody needs to sleep at night. Not many people are psychopaths; the rest of us need to weave stories to tell ourselves that "we're really the good guys".
