I will be the first to admit that I did not think CM Punk would turn heel on this show. However, that's what happened at the end of Raw. I know there are some people that think it wasn't a full heel turn. I disagree with that opinion. There were three things that Punk did that showed him performing heel acts.
1) Punk didn't help John Cena from a beatdown at the hands of Big Show. A heroic figure would help a fallen man. Punk is not a friend of Cena, but he respects him and by not helping him he showed cowardice. The announcers also made a point to mention this, which is again a clear sign of heel behavior.
2) Punk attacked The Rock in a cheap manner. I know some have said that it's not necessarily a heel act because Rock dropped Daniel Bryan earlier, but that was after an annoying heel (Bryan) was running his mouth. Punk's attack was out of nowhere. Rock sold that clothesline like it was the deadliest move in the history of wrestling. Then Punk dropped him with the Go To Sleep. He took Rock out.
3) After the attack on Rock, Punk's face was expressionless. He grabbed his title, he walked out of the ring and he showed no remorse for what he did. While he was walking out, the announcers were also questioning his actions. If he was a babyface he would have been excited, had an expression on his face and looked at the crowd for a reaction. He didn't do any of those things. Why? He's a heel now.
Since his actions on Monday night, CM Punk hasn't posted a tweet. I like that a lot. Let's wait until Monday night at 8pmET (or later in the show) to hear what the WWE Champion has to say. Why did Punk do what he did?
He could say a number of things like how even when he was WWE Champion, a guy like John Cena got to wrestle last on PPVs regularly. He could say that a guy like The Rock doesn't deserve a WWE Title shot at the Royal Rumble because he's not around all the time, unlike him. He'll have to rail on the fans for a bit too because I think it might be a challenge to get people to boo him based on his performance in the last year.
My theory for the heel turn? All he wanted were WWE ice cream bars to come back. And they didn't. Where oh where are his WWE ice cream bars? I'm being sarcastic. Just a little bit.
If you look at this angle long term, though, I think it's for the best. When CM Punk turned heel in the summer of 2009 it was masterfully done and he went on to be one of the best performers in the company at that time. It can be argued that he's better as a heel performer too, so this may be the best thing for him. Sure, a lot of people wanted Cena to turn heel and that could have led to a big spike in business.
For whatever reason (monetary being the big one), Cena's still a babyface. Punk's the heel. The stage is set for a likely showdown at Summerslam. I'm intrigued. Bring it on.
