PrePub - Ascendance of a Bookworm

I think that would depend on the timing and whether he can bring his retainers. Because in my opinion, Wilfried is a good person deep down, but his retainers constantly bring out the worst of him, courtesy to the philosophy of Veronica and her faction, under which they grew up.

If essentially all his retainers, except Lamprecht and Alexis, were replaced with decent and competent people and he'd be given enough time to properly grow up under their guidance, he'd be a much better person than Sigiswald appears to be right now (I don't like what we know about Sigiswald, but we did only get rather limited and biased views of him so far, so I'd rather wait a bit longer, before writing him off as a lost cause). Whether that would make him a good king however is a different issue.

That is an interesting question.. I'm honestly not sure and I think it depends on when. Wilfried Pre-Ivory Tower would likely manage to become even more arrogant and douchey than Siggy currently is. Wilfried post Ivory Tower incident would likely become a puppet but still be less arrogant than Siggy. The closer the point of swap gets to where we are now, the less arrogant Wilfried would become, in retrospective his lashing out against Rozemyne was because he knew she was propping him up and he didn't like becoming Aub because of his wife and not of his own merrits. So I think his mindset at the time would shield him somewhat from the temptations that his new position would bring
