Biden won't pardon; but the Dems won't pursue. They will bury the hatchet. Because not only is it the right thing to do, it is the only wise choice for the Democratic Party going forward not to royally piss off 70-80M+ plus tens of millions of swing voters/independents going forward, etc.
If Trump killed people then OK, otherwise if crimes are monetary and white collar in nature, partisans on the opposite side putting another guy in prison is just too draconian for a non-third world hole country. forget the 60-40 senate majority already likely to happen by 2024, instead, we're talking more into the territory of 67-33 and cons utional amendments in the direction of fascism if the DNC tried to actually put Trump in prison...
