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.
You're imagining something like a thief who just intends to steal $X, robs a bank, counts out $X and leaves the rest of the money untouched. In reality, most thieves are opportunists: they will take as much money as opportunity allows without getting caught.
Obviously you couldn't physically fit $1B cash in a wallet, but assuming this hypothetical wallet did have $1B, does that make the thief more heinous or just luckier?
(If you must insist on a literal and physically accurate wallet in the hypothetical, just imagine it held $1B in Bitcoin.)
