I think *maybe* it Trump came out and gave a full and honest accounting of all his lies--going back through birtherism, including the wall and his taxes, The Ukraine business and his intentions, his lies about the election, his attempts to get Georgia and likely others to change the election results, his lies about Covid, his lies about his finances and how he and his family would handle them while elected, and everything else, then I could support a pardon. If he stood in front of America and said, "I did these things. I lied about them, knowingly and intentionally, in order to manipulate voters or keep power. I did X, Y, and Z. I told A, B, and C lies," then I could probably support a pardon, in the face of a FULL accounting.
As that will never happen, I think a pardon would do nothing to unify us. It would simply let him off the hook and embolden him and his successors and supporters. I think he needs to face full legal consequences for anything and everything he did.
