This consideration seems like it could go both ways. It is true that most people think that intentionally done harm is worse than non-anthropogenic or accidental harms… but they tend to also believe that it is inherently good to punish criminals!
From a ruthless expected utility perspective, it’s the case that we might want to let some criminals out early, because it harms them to be imprisoned. To my recollection this cost was the largest line item in OP’s cost-benefit analysis. But for those with a more justice-orientated perspective, harming criminals is not a disadvantage: retribution is a core part of the criminal justice system and it is an actively good thing to ensure they get their just deserts.
