A large number of decent people do not become evil; they resist evil, denounce it. By definition, a good person cannot be swayed by evil people. Only the morally ignorant and callous can be swayed by evil. Yes, that is the majority; it always has been.
People who have no spiritual growth do not understand this fact. In fact, they deny it, even as it is happening right in front of their face.
Lack of spiritual growth prevents a person from comprehending the facts of evil. A person of worldly means usually has an even more difficult time apprehending such facts.
That a flat Earther has never looked through a telescope does not make their opinions fact, yet how they deny the truth, huh?
