People tend to rationalize it as not that ethically challenging or by compensating through some other societal benefit.

I knew someone who ran a FB group that devolved into conspiracy theories and absurd levels of anger to the point that members of the group were lashing out at local politicians.

The group owner liked the power and influence so rationalized it as "increasing public engagement in politics." This person is otherwise a vegetarian who fosters animals and works in the medical field.
