Zhenya does do a lot of messed up things to Taekjoo, including keeping him captive on the same island for 2 reasons: one he's obsessed with Taekjoo and 2. he's keeping Taekjoo alive (unbeknowst to Taekjoo) since the island is ridiculously hard to get to and the government is doing everything to kill Taekjoo. It's both dark and interesting from a psychological perspective because Zhenya was essentially raised to be a weapon/humanoid attack animal. It's heavily implied his siblings didn't get the same treatment as him and thus don't understand him. His parents also made it VERY CLEAR that they saw him as disposable. He does a lot of bad things, but Taekjoo realizes that Zhenya literally couldn't comprehend what he was doing was wrong and he can't be changed to a normal human being because of what was done to him and accepts that he'll have to teach him. It's also super sad because it's implied Zhenya COULD have grown up into a relatively sane human being if he'd had grown up in a healthy and loving home. He does gain some semblance of normalcy with Taekjoo and Taekjoo's mom though (Zhenya is a big mama's boy and looks out for Taekjoo's mom when he's away) and fu** now I want to cry again.
