I was going to say this exact same thing --- that, as far as the simulation understands, FairBot is just a more complicated Shibboleth.
To properly perform our Shibboleth is to have loved other people, then develop and understanding of murder/genocide and be given an opportunity to express your feeling about it. If these things don't bother you, then you've failed the Shibboleth and need to be killed (or imprisoned) so that you don't damage our society.
And, while our society certainly doesn't implement this perfectly, this is the best you can do. The shibboleth has worked so well because, unless you're a sociopath, it comes out of the root of your being. In my mind, the experience of transcendent love is so powerful that we are willing to reject ANY destruction of it, even if it doesn't directly affect us (i.e. I wouldn't kill a mother because, having a mother myself, I know it would destroy a very power human bond).
