Earlier this week you answered a question about whether or not Jesus may have suffered in Hell during his visit there. Scripture tells us, and as you said, “When He went to the side for the unsaved, it was to preach to them, not suffer with them.”
Why do you think Jesus was preaching to the unsaved? Was there a chance for them to experience some form of redemption, or do you think Jesus was explaining to them why they deserved to be on the wrong side of the chasm?
I should have been more specific in my answer. 1 Peter 3:19 identifies the Lord’s audience as spirits in prison who disobeyed in Noah’s time. From that, it appears that these were the fallen angels who co-mingled with human women and produced the Nephilim. (Genesis 6:1-2) If so then Jesus was probably confirming that their punishment was well deserved. Jude wrote that they’re being held in chains against the day of judgment (Jude 1:6)
In any case, the fact that he was there as an authority figure, not as a fellow prisoner, is made plain in the passage regardless of the make up of the group He preached to.
