Perhaps the problem is actually rooted more deeply.
Konrad Lorenz, a zoologist who lived in Germany during the Nazi time wrote in one of his books that regardless of the political system, it's exactly the same type of people who wants to be a top dog.
When I was a kid, my parents convinced me to join the ski club. It was not about a weekend recreation, it was a sport, all round the year activity. The club operated a kind of summer camp at the Black Sea resort, and in summers we were sent to there for intensive training. The club fee was nominal, so there were a training days and a working days, when we were doing an agriculture work at the local collective farm, usually in the field. It was considered a part of endurance training, because the soil there is baked by the sun and it's really hard to dig it with a hand tools. So it required motivation. That was the main problem. It's hard, sometimes it hurts because it's sport and all the enormous efforts with the only purpose to prepare for the competition, when the winner will have a good day while the looser will have a bad day. Essentially, it's all about how to arrange a bad day for someone. There were many boys who were enthusiastic in doing so. But something inside you must resonate with that, otherwise, no inspiration. So my sport career was short. Still have no idea why so many people liking to be in the huge crowd, accepting the risk of dying in stampede, willing to pay the ticket price to watch a competitive game and to play apes together. That only benefits those in the box office.
Later, with the military, I took responsibility for the small team, call it a motley crew, because of its multi-ethnic composition. There were three guys from Western Ukraine, one Latvian, one Belorussian, one mixed blood Gipsy from Karelia and me the only Russian. From time to time, I reminded them that it'll be better to obey my orders with no hesitation because I'm not happy to issue an orders and always thinking about how to issue a bare minimum amount. So if they will not comply then I'll be replaced with another commander, who's of different attitude (a lot of examples around) and they will have much more work to do. It's like in prison. No of us wanted to be here. Usually, that worked well except for one individual who was just stupid and preferred to play rebel regardless of the circumstances. Bit that was more of personal feud. There is always at least one such guy in any team. It's interesting the Gipsy guy had served one real prison term prior to the draft (and one more after the discharge, AFAIK), but he was my best friend there. Probably because he was also not happy with the social system and tried to fool it, he just took wrong approach. Anyway the barrack is a perfect place to watch the human social behavior. It was amazing to see how a humble scared boy quickly develops or reveals his dictatorship nature when he's given the right to tell others what to do. Frequently, it was hard to predict.
So if the Galactic Gremlins are going to do the great cleanup here, one possible plan would be to help people to construct several huge stadiums in Cyprus. This island has a warm climate and is of enough area to accommodate a crowds comprising all billions of human population. Let them all to voluntarily flock there to watch a free sport show. And then a limited number of nuclear explosions above will finish the species. A minority that survived by missing the show is likely less social and competitive and therefore less harmful.
