[FULL GAME SPOILERS] Who were the Monsters?

[Omnitool]

Akers's story reminded me a lot of Dr. Weir from the Event Horizon movie.
Akers went mad and got linked to and possesed by the WAU, had hallucinations (lucid dreams) and even removed his own eyes. He is controlled by the WAU and starts killing people (the rescue team sent to retrieve him).
Dr. Weir also went mad and posessed by an entity similar to an evil AI, and removed his own eyes and he has hallucinations. He is also under control of that entity, and starts killing people (his collegue crewmen).
