there are 40* people who could receive the commutation, I don't think it's outlandish to suggest these people should also not be killed, if you believe in the death penalty fine, but Joe Biden is apparently a devout Catholic who at some point didn't believe in it so what's stopping him from commuting all the sentences

As a presidential candidate in 2020, Biden promised he’d be different. His official platform provided unequivocally, “Democrats continue to support abolishing the death penalty.” The Biden-Harris 2020 campaign website promised, “Biden will work to pass legislation to eliminate the death penalty at the federal level, and incentivize states to follow the federal government’s example.” The position was bold, clear, and absolute.
