To add to your (excellent) points, he only started tweeting about peace once it was obvious the plan (interrupting the certification to use "alternate slates") had failed. Of course he would share a "call for peace" at that point. Everyone with half a mind would. It didn't cost him anything (beyond his ego), and it has allowed his followers to do exactly what GP is doing - leaving out all the incriminating information.
And three of his tweets were deleted by Twitter, including this gem from late in the day:
“Mike Pence didn't have the courage to do what should have been done to protect our Country and our Constitution, giving States a chance to certify a corrected set of facts, not the fraudulent or inaccurate ones which they were asked to previously certify. USA demands the truth!”
This doesn’t read like someone who was remorseful about the actions that happened that day on his watch.
