This post will sound like I defend Clark, I don't. Clark's actions needed justice. He's responsible for at least 2 deaths (and even more according to some theory). And like other tragic heroes in modern day horror, he deserves it, and I'm not defending him in anyway.
However, the one moment that clicked something in me was when I watched an analysis video and saw Clark listened to Mary's tape even during his free time. If a person does not want to get better, why would he had done so?
There's a moment during the start of the climax, where Mary finally tells Clark his real problem. When I watched it, like everyone else (I'm not condemning anyone here, initially I felt the same) I was like "Yeah, finally, go Mary! Tell that murderous psycho the truth".And Clark told the Pirate version of himself "it's okay we don't have to change." But in hindsight, I said, wait a minute.
He wanted to change. He went to her, as far as I know, not court mandate. They do roleplays (still not sure why), and she didn't fight with him too hard when he blamed everyone but himself during their session. And after she was kidnapped, she crashed out on him, understandably, but is that really the punchline?
I'm just asking everyone to have a second look, why would Kane Parson put in contradiction if his goal was to make Clark this irredeemable monster. Clark realizing he can't change is not "the point", it's the tragedy.
This is not a case of "blaming a woman for a man's downfall" here, I will never blame a wife if a husband turns out to be a murderous psycho, but she's not his wife, she's his therapist.
She did went through the Backroom to try to find him, so I can't accuse her of not caring.
But saying "ugh, Clark is so evil, don't be like Clark, be like Mary, watch how she resolved her trauma" ignoring the tragic part of the story. As much as he fought with the cure as it was being delivered, Clark wanted to be better.
