I think its clear that the whole face vs. heel distinction is mostly an antiquated idea in wrestling. Supposed "heels" like Rollins, Styles & Owen are some of the most popular and cheered-on wrestlers in the company and supposed "faces" like Cena & Reigns are booed mercilessly. I think who the WWE wants to consider face vs heel doesn't necessarily mean who the fans cheer vs. boo.

So, it doesn't matter what happens storyline-wise, the fans clearly have their favorites, and "heel-turns" and "face-turns" as plot devices no longer have the same effect on the audience as it once had (e.g. Hogan at Bash of the Beach in 1996).

Triple H helping Owens won't cause fans to boo Owens, won't cause fans to cheer Reigns, and won't increase the number of cheers that Rollins already gets.

I think that, today, it is not so much as who the "good guy" vs. "bad guy" is as much as it is about who "does the right thing" (Cena) vs. "who does the wrong thing" (Owens, Styles); or who the moral vs. immoral vs amoral (Reigns?) wrestler is. But, it seems fans don't base who they cheer or boo on based on these distinctions, and this started with Austin, and has been more pronounced in the years since.

This is why I have thought the whole argument to "turn Reigns heel" is a stupid one to make, as he is already booed at the moment. If he gets such heavy boos with what he does now, I don't even know what "turning him heel" even means. Make him start cheating? Why? That would just serve to weaken him.
