Yes it is his fault, hes not trying to be a heel in anyway whatseoever and decided he wants to be cheered
What good non monster heel goes out, beats the babyface in a straight up fair brawl, busts him open, plays to the crowd for more cheers and leaves him laying?
He couldve just as easily had the lon beat roman down and then came out and had them hold him while he beats him up and bloodied him.
Instead he came out with music, looked the babyface in the eye and kicked his ass
He sacrificed roman, plain and simple.
He got knocked to the floor, stumbles around, grabs the ring bell and hit Roman with it, then took over from there... how is that beating him up in a fair one?
