From what I understood, Awen knew Hannibal before the experiment on a personal level. The experiment Hannibal concocted made Awen an accomplice in his suicide plan and basically left him with eternal guilt for killing his friend unknowingly when he was trying to help. I think that's key because that was a really shitty thing to do and something you should never do to someone. If we were to consider that Awen did not know Hannibal at all and this occured, he could remain in good faith that he tried his best even though he was unaware of the exact circumstances that created Moloch.

Reading the analysis provided, I see the path that you are trying to question. As a person suffering from a dissociation disorder and having therapy and counselling for it, I can relate to Hannibal and Moloch quite a lot. That's why it's more unacceptable to me that he did that to someone that knew him. I don't think Awen is to blame and all we can hope from the people we seek help from is that they understand the language by which we speak and show our struggles - especially in my case stories and metaphors. And that they understand and can sympathize a bit with it in good faith to help us. I have met some who are like that and who really didn't care what I said if only to use it to mould it into doing what they wanted. No one can understand 100% what someone else is struggling with especially internally. All a therapist/counsellor can do is keep trying to help them, apologize when you realise you have done something wrong even later down the line and build a bond and be there for them as long as your allowed/can to.
