Has Coach Hong Myung-bo done absolutely nothing right?

I don't know much about football and I'm not really interested, but since Coach Hong Myung-bo is currently being criticized to the point of being treated like a national traitor,
I'm curious: is there really not a single thing he did well while coaching the national team?
People say even Park Chung-hee and Chun Doo-hwan had things they did well...
Coach Hong Myung-bo also intended to do things wrong... Is there nothing, even something like a task he ended up doing well due to his own mistake?
