The one question Rogan won't ask is why he felt the need to go full juicer against Sakuraba. One of the weirdest moments in the history of MMA. If there was a dude who I would've said wouldn't take steroids, it was Royce. It was one of those moments where I thought well f$ck, everyone's an asshole. Royce is human, but damn it sure was disappointing.
Rogan doesn't need to ask the question because he is very knowledgeable on the subject. It is only weird and surprising to you because you don't understand what "steroids" actually do or why athletes take them, nor do you have any interest in hearing or learning anything about that reality because it doesn't fit with your desire to demonize athletes over it to discredit their accomplishments.
