I think it's meant as that being amazing in the job shouldn't be an excuse for being a terrible person.

While I generally agree with the post (I only skimmed it yet), I am skeptical that it can be completely realized. There are many examples from history of terrible people succeeding, because they were really good at their jobs. If a community gets rid of them completely, it will put itself at a disadvantage. You know, evolution/game theory is a bitch and all that.
