The same is evident for the truth of the authority of the Bible ...as God's Word.  Those who don't believe in the authority of the Bible would have little motivation to read it ...and if they don't read it, they cannot know of its truths.  And there is also a very negative campaign to discount anything that is said by those who do know those truths.

Only God is good ...and good only comes from God.  What happens if we don't know God?  If we don't know God, then we really don't know good.  If we don't have knowledge of God, we don't have knowledge of true good.  And without guidance, things tend to get less good.

The more 'wrong' that becomes commonplace, the less it is considered.  We're not talking tomatoes ...their have been tribes who have eaten other people.  It would take a tremendous departure from God to accept cannibalism, but if you belong to the tribe and it is commonplace ...it would be uncommon not to be a cannibal.  So, what would it take to change all that?

It doesn't take something as extreme as cannibalism to achieve a gross departure from God.  Yet, we often defend, with more understanding, the departed whom we have failed to help draw close to Him.

Many people sympathize enough with the people who perhaps do not know God, but seemingly not enough to invest time in helping them know Him.

Followers are followers.  Often followers don't really know the conditions of the following ...but, they nonetheless follow.  With the angels, it was clear ...either with God, or with Lucifer.  There was no peace, and something had to be done to restore it. We all participate in a war that we mostly know little about.  But, we also think little about when we make choices that are against God's way ...it is called sin.  And to not fall to the same judgment as Lucifer, a righteous and loving God offered His Son.   Jesus died for our sins. And we have somewhat the same choice as the angels had ...to follow God, or not.  If we don't accept the tremendous love of a Son who died to make it possible ...that is rather ungrateful.
