From what I read Biden didn't seek that judge to pardon, he was just one person affected by some big mass pardons. In this case I think he was one of like 1500 people who were moved to house arrest for non-violent crimes during Covid, who Biden pardoned all at once.
Still not great, the administration should've reviewed the details of those cases first, but it's not like he deliberately sought the guy out.

The job of President is complicated. It is not remotely possible to go over every single detail of every single action. Every president makes whoopsies, I prefer to give benefit of the doubt between mistakes and malice. There are plenty of intentional things to criticize without sensationalizing this sort of thing
