By Lorelei’s analysis, Cormoran Strike was a fundamentally damaged and dysfunctional creature standing in the way of his own happiness. He caused pain to others due to the essential dishonesty of his emotional dealings. Never having experienced a healthy relationship, he ran from it when it was given to him. He took those who cared about him for granted and would probably only realise this when he hit rock bottom, alone, unloved and tortured by regrets.
