Pro-mortalism is the rather unpopular view that it would be ethical to kill all humanity instantly and painlessly to prevent further suffering if that was feasible. Sam Harris and David Benatar reject this view in a recent episode of the Waking up Podcast, and R. N. Smart's also attacks it in his "benevolent world-exploder" thought experiment. Does anybody know of a philosopher who actually openly subscribes to this view?
It's easy for me to see why somebody would keep such an opinion private, since there's a lot of stigma around it and I think many universities and institutions would prefer to avoid associating with people with these views, so some philosophers may avoid this in order to preserve their reputation. Also, it's hard not to be diagnosed as depressive by your interlocutors, leading people to start investigating and speculating about your personal life. But I was wondering if anybody has been brave enough to face all these obstacles and "come out" as a pro-mortalist.
