To answer your question,

the things you mentioned are all part of the lie that they will believe. People who refuse to repent of high-handed rebellion become insane, and think right is wrong and wrong is right. We see that all around us. When they refuse to be thankful, and to worship and serve the Creator, God turns them over to a reprobate mind (Rom 1).
