Kinda disagree on the latter part. If there's no chance to toss them in prison, but other opportunities, do whatever is necessary to prevent further suffering.
But then there's the question on whether you could trust your own judgement.
E.g. I wonder how many people would choose Kim Jong Un without realizing how EXTREMELY progressive the guy is on the scale of the hell hole that is North Korea.
Allowing just anyone who wants access to the countrwide intranet with some curated and heavily censored information from the outside and ending the crackdown on user generated content? Blasphemy! Allowing a selected few foreign restaurants to open up? Witchcraft! Building semi-normal housing in the prison camps you toss entire families together with their children, grand-children and elders in? Cracking down on systematic rape and arbitrary mass executions in those camps? He's going to come for our (prison) children next! Trying to shut down the practice of high ranking officials forcing young girls into sex slavery squads? And even after inflicting an "undisclosed physical ailment" on him, he still only barely agreed to restart the squad, controls the selection of girls himself instead of allowing us to force anyone we like into it, requires parental consent, makes us wait until the girls receive an education and doesn't recruit anyone under 14 anymore? SCREW HIM!
And many other things that seem absurd to us and the Juche system for exactly opposite reasons. Like allowing other countries but China and Russia to offer work in their special economic zones, agreeing to a meeting with the US President at the border inside NK, considering negotiations with South Korea and allowing very limited cultural exchange, giving some priority to increasing living conditions for anyone but those who have the priviledge of living in the capital, turning a blind eye to tiny private markets selling some less controversial contraband, ....
The guy is just barely holding on in a system that completely vaporized anyone with even but a tiny bit less than utmost loyality to the Juche ideology. For several generations. All institutions, government bodies, civic organizations, education and corporations are under complete control of Juche extremists. And then there's this one basketball obsessed fatty raised in Switzerland.
His greatest achievement so far is probably opening up their intranet to about a quarter of their population (less than 1% were allowed to use it before him) and slowly expanding the group of people who have access to the outside internet. At this point more people have access to smartphones than to television or radio. And now social media and chatrooms are apparently being reopened after the previous government took those from the 0.1% elite who had access to the intranet back then in 2005, because they organized a spontaneous sport event with a few hundred people.
And not long ago the NK government became very worried about people accessing the global internet through their intranet enabled devices, extending the application used to connect to the intranet with spyware trying to detect foreign network accesses. So it seems VERY likely to me someone hard to stop is currently hooking their intranet to the global internet in the background. And the NK establishment is not very happy about it.
Maybe the life of North Koreans will become much better within one or two generations.
