#1 Why was the Ramblin' Rabbit killed?

Daniel Bryan might just be The Fiend's best rivalry since he made his in-ring debut last August. It's had a lot to do with his character work and as usual, he has continued to prove why he's still among the best in the world.
As with the other rivalries, this one is personal and involves a lot of mind games. What was interesting was the backstage segment where the Ramblin' Rabbit, who is believed to represent Bray Wyatt's previous persona (The Eater of Worlds, not Husky Harris) told Bryan that he knows how to beat The Fiend.
Bray Wyatt shut him up and warned Bryan, later giving him a "gift", which turned out to be the Ramblin' Rabbit with his head half chopped up. It was certainly brutal and likely represents the key to beat The Fiend, which we won't know soon.
However, our theory is that it has to do with Wyatt's old, more vulnerable and beatable persona. It's a brilliant bit of character-work from Wyatt which we believe will play out over the next few months - including the involvement of The Fiend's next challenger.
