Yes, yes, a thousand times, yes.
Let me take this one step further. In the not so distant past, John Cena was involved in an angle at Survivor Series 2010 with Wade Barrett. In this angle, known as "Free or Fired", Cena had been forced to be apart of Nexus, because he lost to Barrett at Hell In A Cell. Barrett had made Cena's life a living hell, and Cena had helped Barrett become Number 1 Contender. In the angle, Cena had to referee the match at Survivor Series. If Barrett won the title, Cena was free from Nexus control. If Barrett lost, Cena was fired from WWE. Barrett's opponent in that ever important match? Randy Orton.
Yes, this is the same Randy Orton, that, the night after Summerslam 2007, kicked John Cena's dad in the head. He later faced Cena's dad in a match with Cena handcuffed to the ringpost, forcing to watch as Orton methodically beat his dad down, before RKO'ing him unconscious. He was about to punt him again before Cena escaped from the ringposts.
Anyway, why wouldn't Cena screw Orton here? Promises to be an unbiased referee my ass, would you be able to be unbiased towards someone who beat on your dad several times? Three years later be damned, I'd never be able to co-exist with that person again. Yet Cena actually pushed Barrett into Orton, allowing Orton to RKO Barrett, and then he counted the three. So essentially, he cost himself his job for Randy Orton(and his integrity, I know), the man who had brutalized his dad.
The two have teamed together multiple times since Orton turned face, and there hasn't been a sign of dissension between them. I know we're to suspend disbelief and have short memories as wrestling fans, but this was too much for me. The most nauseating thing to me? After Cena gave his fairwell speech on Raw the night after Survivor Series, he hugged and shared final pleasantries with the entire roster. The last person he came across was Randy Orton, and they hugged. It was as if their feuds in 2007 and 2009 never happened, and Orton had never targeted Cena's dad. How absurd.
So yes, I'm all for this. When there are personal feuds, they shouldn't be forgotten. I loved last year how when Cena was teaming with the recently turned Alex Riley, and he said something along the lines of not forgetting what Riley did to him when he was with Miz, and not trusting him.
I wish all wrestlers were booked this way, with long-term memories. It would add to the realism of shows and make the wrestlers seem so much more authentic and real.
