It is important for Western observers to understand that this New Left in South Korea is the same old Trotskyites of the 30's in the US and with the same effect. Rather than vigorously oppose the totalitarian regime in the North they sought accomodation. Their moral standing descended from there.
Yep, they will cement their reputation as collaborators of mass murderers on the level of Stalin and Hitler.
They have to weave endless excuses and lies to deflect their responsibility. Many of them show by example what the 'banality of evil' is about.
