I see people complaining for how the story turned out, but the environment was already toxic and violent. Matthew has shown marks of his strength and temper and how possessive he is of Jin and of the things he considers his, even as a child. It is only natural that Jin rejecting him would trigger him. This was a very dark and violent story from the beginning, not expecting a scene like that is unrealistic.
Tbh, season 3 felt more like a side story/ epilogue. Not that I am complaining....
Also is it just me, there was a character that looked like the top, but he was a bad guy. Did I made this up?
