Ok serious talk yes Vecna dropped the affable mask immediately. Yes he is of course lying on a lot. But I actually think they changed him a bit for the show and he actually believes he is "saving the world" on some level. Even if it's mostly spite in truth, even after ascending he talked about that.
Campaign Whispered One was already a lich and was very aware he was evil and fine with it. Show Whispered One is... still clearly evil and delulu but I think he wasn't a lich until now (dying to be reborn is standard lichdom and all in his backstory seems to suggest he was just a powerful necromancer messing with things who got put in wizard jail so I think show Vecna actually put Lichdom and Ascension ritual all in one) and his backstory and grievances matter a lot more to him. He wants to "save the world" to prove he was right and he is evil and spiteful about it, campaign Vecna was like "yes i will enslave you all lol"
