I loved how euthanasia was looked at from different POV. Doctor’s POV as more of a morality issue. Boss’ as the wrong way to perform it. And Thui’s legal POV. Both Kan and Boss had good intentions but Boss had no right to do it, literally killing people, on the other hand Kan respected wishes of the patients, which would make it legal somewhere else. Thiu holds the opposing views to theirs, he looks at it from his professional POV, which makes euthanasia illegal and unacceptable for him. I think it gives us all a side to be on (well maybe not Boss’s side, I think, he’s just an example of how it shouldn’t be done) and for many it opens a conversation regarding euthanasia since it’s illegal in most countries. I really didn’t want it to end like that but I think it makes sense that Thiu arrested Kan, I don’t think he could live with himself, knowing that Kan continues euthanasing people, in his eyes and according to law it is murder and from how I understand the character, he thinks it’s his duty to act according to law (and I mean it is his job). I still hate that Kan got arrested tho.
