Deckard Cain: Not corrupted, but evil to the core? Alright, I searched around the forum for a bit and found some other people speculating on Cain being an antagonist in D3 because he allegedly may have been corrupted based on a vague comment in the FAQs. I have a somewhat different theory that a friend spelled out to me and strangely enough it makes sense and would be an insane plot twist . The basis of this theory is that Cain is actually the highest evil entity in existence, I guess Lucifer or Beelzebub himself. His ultimate plot is to help the heroes in defeating the Prime Evils so that once they are gone nothing is left (except the hero which will be caught by surprise) to stand in his way for ultimate power. Think about it.. Mysteriously he was the only surviving Horadrim, and has intimate knowledge of nearly everything dealing with both heaven and hell. Furthermore, he was also mysteriously the only person left unscathed when Tristram was destroyed. Hanging in a cage? Pretty poor showing of terror by the dark demonic fiends of hell. One more piece of the pie here is his name. Cain... Hmmm perhaps he is supposed to be Cain as in, Cain and Abel, the first murderer? Interestingly plausible if you ask me Feel free to completely disagree and debunk this but please give good reasoning - All added thoughts welcome.
