Daniel's Fate

Back in the Chamber where Daniel was with the Experimenter, Daniel didn't seem human anymore.

The Experimenter asked Daniel, who he was? to which he responded I am the Devil, in a really creepy voice which sounded inhuman.

The experimenter was shocked, he didn't expected such results. When the soldiers came in to fetch Daniel he attacked them violently like an animal hungry for days and killed them before he himself being killed by one of them.

The Experimenter locked himself in the chamber due to regrets and shock, he didn't wanted to get out now.
