It's just unfortunate that Trump, and now, excessive pardons are politically polarized, which could cloud the fact that justice was done today. I don't credit Trump in any way for doing "the right thing" or even having a principled position regarding Ross' case. Clearly, others with influence on Trump convinced him to sign it. It doesn't matter how the pardon happened. Biden should have already pardoned Ross because that crazy sentence shouldn't have happened in the first place.
I get that there are different views on how much punishment should be based on intent vs outcome. My opinion is factoring in outcome in criminal sentences is often pragmatic, but if we had omniscient judges, judging on intent would be ideal.
