South Korea was a brutal dictatorship for quite some time, just because they aren't now doesn't mean the US's military intervention is to thank for that.
Multiple brutal dictatorships, which were a direct continuation of Japanese colonial control, and which massacred their own people with US support and approval.
> In the fall of 1946, the US military authorized elections to an interim legislature for southern Korea, but the results were clearly fraudulent. Even General Hodge privately wrote that right-wing "strong-arm" methods had been used to control the vote. The winners were almost all rightists, including [Syngman] Rhee supporters, even though a survey by the American military government that summer had found that 70 percent of 8,453 southern Koreans polled said they supported socialism, 7 percent communism, and only 14 percent capitalism. [...]
> Chung Koo-Hun, the observant young student of the late 1940s, said of the villagers' attitude: "The Americans simply re-employed the pro-Japanese Koreans whom the people hated." [...]
> Seventy of the 115 top Korean officials in the Seoul administration in 1947 had held office during the Japanese occupation.
> In the southern city of Taegu, people verged on starvation. When 10,000 demonstrators rallied on October 1, 1946, police opened fire, killing many. Vengeful crowds then seized and killed policeman, and the US military declared martial law. The violence spread across the provinces, peasants murdering government officials, landlords, and especially police, detested as holdovers from Japanese days. American troops joined the police in suppressing the uprisings. Together they killed uncounted hundreds of Koreans.
> American anthropologist Cornelius Osgood, spending much of 1947 in a village west of Seoul, watched as police carried young men off to jail by the truckload. A "mantle of fear" had fallen over once peaceful valleys, he wrote. The word "communist," he said, "seemed to mean 'just any young man of a village.'" On August 7, 1947, the US military government outlawed the southern communists, the Korean Worker's Party. Denied a peaceful political route, more and more leftist militants chose an armed struggle for power.

The alternative was that the entire peninsula would be "North Korea". And then there would never be any chance of formulating a functional democratic society.
You don't know what the alternative would be. US intervention and the massive amounts of civilian deaths caused in Korea are a major reason why North Korea is so anti-West.
There is no good north korea timeline. The entire revolution that created it was for the express purpose of putting an idiot dictator in charge, one who immediately went to work on forcing the population to consider him a god king and putting his equally selfish, stupid, paranoid, and vile progeny in charge.
Unless you believe a unified korea without US intervention but still with USSR support would suddenly overthrow that repressive regime, that was never going to produce a free society.
Why would they be less authoritarian if they weren’t anti West? This sounds a lot like the argument that the only reason communist countries terrorize, murder and starve their own people is because of the evil capitalist in other countries who aren’t doing that to their people. If only we could execute all of the kulaks together there’d be no need for the NKVD, comrade!
Lest we forget, the North was propped up by the Soviets under Stalin. Do you think it is likely that they would have allowed a non-Stalinist, non-totalitarian faction to remain in charge there even if there was one with strong positions? Just look at Soviet-run purges of "improper" leftists during the Spanish Civil War.
