Nahh, I don't feel like Varis has anything to do with the way Zenos is right now. During his talk with Elidibus he says something like "monsters are not meant to rule.", meaning that he is not ok with the fact that a monster like Zenos is rulling places right now, but he can not do a thing about it since that is his blood right. Now, ever since Zenos was born he was meant to rule thanks to his blood, so if Varis does not think a ruller should be a monster, then why would he raise a monster to rule? I think he only raised Zenos in a way he could be strong and determined and Zenos by himself turned into the beast that he calls himself.
