Even if Pence had (for example, as a political decision after collecting insufficient contrary information due to blue state stonewalling, Soros-AG corruption, and SOROS state SOS investigational competence) eventually accepted Biden-electing election results, the precedent would have been set to place corrupt states and the bad actors who populate them under a microscope for federal Electoral College purposes.
Over time and multiple election cycles, this would likely have the effect of wiping them clean. Like with a cloth.
That is one of the good outcomes that we could have had by Pence doing his duty.
Another would be to put a taint on the legitimacy of the Biden administration, and thereby keep people talking about his corruption and the rigged election that put him there.
Having the public view Biden as illegitimate would have improved the political dynamics of holding everyone accountable that put him there.
The world would have been a better place if the entire public viewed Biden as illegitimate.
Pence lent him a veneer of legitimacy.
