In wrestling, heels are the "bad guys". Typically, they avoid the confrontation with the good guy. They are cowardly, they cheat to win, they lie and gloat. Neither Undertaker or Wyatt fit this description. They torment the faces, but never seem cowardly when doing say. They welcome fights rather than run from them. Both have had people interfere on their behalf in matches, but both have instructed their followers in the past to stay out of fights when the situation called for it. Both have cheated to win matches, but neither man gives the impression of NEEDING to cheat to win. They cheat because they wish to inflict pain on their opponents. And neither is a liar. When you're beating the good guy into the ground, you don't need to lie.Look at Bray's career so far. He's been in Cage matches and Ring Of Fire matches against bigger, stronger guys than him, and not once has he ever shown one iota of fear. Even when his followers are losing their heads, he just laughs at you. Rather, he delights in pushing the good guy's limits, seeing just how far he can push them until they become monsters like him. He will even wear his opponent's merchandise if it means getting under their skin. It's very reminiscent of The Joker's relationship to Batman in the DC universe. You will play the game Bray Wyatt's way, whether you realise it or not.
