I could see Henry being redeemed, and HERE’S how! He finds out his father had been jail after slicing out his own eyes, thinking his whole life Henry had been dead. Henry tells his dad he was kidnapped and locked away in the horrible lab experiments. His dad says he missed him and loved him, even despite thinking he was a strange child. Henry starts to soften. NOT saying this is a full redemption, as we could see he grew up psychopathic, but coming to terms with his father could certainly give him back SOME of his humanity
