Except he wasn't offering the stance on Blood Magic as his opinion.
He're the quote: "Cameron: Blood magic is an interesting one. Pure blood magic in the lore of the game is really supposed to be a very evil power. In previous games it wasn't really perceived to be that way. We talked about it being that way in the lore, we'd talk about crazy mages who went down the blood magic route and how that would have nasty consequences. So in Inquisition if we can't bring that across, that consequence across then we won't do it. We're looking at a couple of different options that still give that quasi-evil kind of fantasy element without trying to go into the nitty gritty of blood magic conflicting with other elements, but we haven't landed on which one's going to be there."
Cameron Lee thinks it's evil. We have two games that call this into question. As early as the Magi Origin, we even have Duncan disagree with what the mage protagonist says if the player chooses to say that it's evil. The Joining and the phylacteries are technically blood magic, and we see Finn using a blood magic ritual to locate the Eluvian located in the Dragonbone Wastes. We even have a companion in the sequel, Merrill, who is a blood mage, but isn't using her abilities for anything remotely evil.
That's an OOC Development choice. At no point does he say "I". He consistently says "We". That's at least one, and probably more, discussions amongst multiple people on the dev team on the nature of Blood Magic and what to do if they can't get it right and finally show the consequences of using it. It's a specific statement on their reasoning and the probable end result. A result, by the way, that actually came to pass with the removal and replacement of the Blood Magic specialization.
Developers disagree all the time, even about issues pertaining to the lore - you know this. We have Gaider saying that the Dalish live longer than the city elves the more generations they live away from humans, while Kirby said otherwise. Your disingenuous attempt to make it seem like the developers are always on the same page is noted. You're blatantly dismissing what we know from two games to cherrypick one single interview, despite knowing full well that it's a contested issue. Even the World of Thedas doesn't say that it's inherently evil.
The developers see it as evil. They wanted to make sure they could show it with the proper consequences, or they would remove it. They removed it.
No, Cameron Lee sees it as evil. We have two games and a book introducing readers to the World of Thedas that calls into question that opinion. Instead of trying to take a shot at me by making an inaccurate comparison, maybe you should stick with the actual topic at hand?
