Kane’s beatdown of Bryan

Doesn't Cena come off as an asshole for not running out to help Bryan?  While, Daniel can normally defend himself, they purposefully set it up that:
– Kane was an uncontrollable monster
– Brie *ran to the back*

Are we to believe she ran to the back and didn't grab the guy dating her sister to help?

Shouldn't Cena have at least come down at the point where Bryan was clearly defenseless in a neck brace on a stretcher and his life was in danger– and still getting pounded?  

​Everything you are watching is fake, except for what you watching RIGHT NOW, which is real.  Also, Total Divas does not exist.  
That's all I got.  ​
