OK, lets skip all the moral and legal arguments by assuming you are working on a cure for the zombie plague and all the devs work 24/7 for their share of the last remaining pure water to meet the approaching (un)deadline.

So you find some bugs in v1 of the cure and look around to assign someone to fix them. You have been bitten too, so you need to get this finished and not upset The Plan as much as anyone else.

Do you choose:

• Developer A  : He missed a semi colon due to tiredness and is the cause of the bug.
• Developer B  : Superfast programmer finished his task early and got a good nights sleep.
• Developer C  : Newly trained dev, super keen but low experience means high risk of mistakes
• Developer D  : Been here ages and almost fully a zombie, disliked by the team. no moral penalty, but takes ages to get things done.

The point is of course that you want to get the quickest/least risky solution to get the job done. Not play some weird morality 'hunger games' with your employees.
