Then only extremely socially minded people would dare to do the job.

There was a similar sci fi story I read. At the end of a war the rule was that all allied ( not enemy ) generals would be executed. The idea was that war was such a horrible concept that to lead one would require extreme sacrifice and social consciousness on the part of the leaders. War was legal and to be fought without limit however on conclusion all leaders would be put to death. I don't remember the author or the story name.
