What about Eddie? I was kinda bummed that he didn't get a mention. He was very intrinsic to James' realization of his own capabilities. He also appeared to have some mental or social disorder, which likely made it easier for him to fall into such a cold-hearted and isolated place as a response to the mistreatment from his peers.
I always felt able to connect to all three of the "tortured souls" on a mental level, so I tend to have a sympathetic feeling for him, at least more so than what I usually see from others talking about him.
Great article. I think Eddie was not included because the intention was to highlight James mental illness and his relationship with Angela. Eddie and James got a different relation, they didn't share deep thoughs, they just talk under the surface and James only realizes about Eddie's mind in the prision. But Angela really interact with James, causing the transfer of her monsters to he, as daddy. At this point, Angela's illness matters to the story and the game.
The author could mentioned Eddie because there is a point when James told him - you can't kill people just because they laught (or something) - to kill because an awkward motive caricaturated, and than he feal real bad after to kill him, even with a rational reason. Situations that fit with James reality, he murdered his wife by (initially) stupid reasons and than regretted, even (in his mind) with rational reasons. So Eddie matters less, but matters to James endeavour.
But I agree with the author about the extreme well made stories about James and Angela illness.
