I think Kang Dong Won's character Jo Yoon - although truly the worst of the worst even amongst the bad guys in this movie - still managed to make you feel some sympathy for him. It transpires that, as a child, Jo Yoon was treated terribly and was also abused by his family (I WON'T say more because I won't spill spoilers) and because of this it went on to twist him into a really terrible person. I really cried for him when he was talking to his father because you could see, in that moment, how different he could've been; and even he acknowledges that he was this way because of what he suffered. Jo Yoon also did still have moments of humanity when some compassion showed through (however briefly and rare they were). Kang Dong Won really knocked this role out of the park; for me he was the one to watch and completely stole every scene he was in. You were obviously rooting for the Robin Hoodesque heroes, but you still felt sorry for him. I really felt that he would've been as good as he was bad if his childhood had just been different. Kang Dong Won really is one of my favourite actors because even his 'bad guy' roles are never played as two dimensional villains; he always adds a depth to them that makes you think and you never just see them as 'bad' - there's always more to their backstory.....if he's in a production these days I ALWAYS set out to watch it, he's so good.
