They might be too far gone. People that worship Trump and laugh with glee when ICE murders an American who is surrendering to them makes me think of 2nd Thessalonians 2, 9-12:

The coming of the lawless one is according to the working of Satan, with all power, signs, and lying wonders, and with all unrighteous deception among those who perish, because they did not receive the love of the truth, that they might be saved. And for this reason God will send them strong delusion, that they should believe the lie, that they all may be condemned who did not believe the truth but had pleasure in unrighteousness.
