This reminds me of the idea that the nuclear codes can only be accessed by the president if they personally kill someone to get them. The idea is that it takes the idea of abstract power and translates it to a much more emotional decision.

I think there are certain aspects that appeal to that as a natural bulwark against power. But I’m not so sure we should want such decisions to be emotional. Just like we want justice to be blind, I think it may be a good idea for it to be dispassionate as well. This is why we generally frown on countries that let the victims determine the sentencing of their perpetrators.
