They just booed Orton winning. They also booed the HIAC match ending but still cheered the Fiend like crazy. They also booer Goldberg for beating the Fiend even though he was cheered before beating the Fiend, but cheered the Fiend. And WWE also edited away the boos so they don't care because they can now control everything.

Also, WWE is not meant to be realistic. If you want realistic, go watch NXT. And NXT is also the least popular WWE brand because of its realism. It has always been silly. It's why WWE succeeded & all the territories fell down. These supernatural characters are selling them merchandise & getting views. Wonder why spooky characters like Aleister Black didn't sell as much merchandise as the Fiend? Because he wasn't using supernatural powers like the Fiend. It sells.
