I’m not sure I trust any of these claims. The sources are all Ukrainian which means they are highly likely to be war propaganda at worst and heavily biased at best. No matter what anyone’s preconceptions about North Korea or Russia may be, independent verification is needed to know if any this is true.
They aren’t being obtuse. They’re just an idealist. They likely believe the decisions people make and the things they choose to believe in are detached from the circumstances in which people find themselves. In their mind, morality is self evident and anyone committing an immoral act, as they define it, could simply choose not to.
