Imagine you are visited one day by a higher power who tells you that they have been monitoring the Earth and are alarmed by the amount of suffering that exists amongst the human population. They tell you that they will return after a suitable period and that, once only, you can tell them the names of the 10 people who you think are most responsible for this suffering. They will then arrange for those people to be painlessly removed from the planet and euthanised.

Do you think the world could be made objectively better by removing these 10? If not, how many do you think it would take? 100? 1000? Who would you nominate? I suspect that the final list would be mostly unrecognisable African dictators or various anonymous business leaders rather than the Trumps and Putins. I also suspect it would take many more than 10 to move the needle.

btw, I would have absolutely no ethical or moral issue with providing the names.
