I concur with the OP. It is not the biggest surprise to me that Ketheric is an antagonist and probably one of the three underbosses which were shown on the bridge, because he played a prominent role in Big Jim Halsin's sermon. So I can accept the spoiler. But I don't want to know the rest, I want to explore and be surprised.
BTW never heard of J. K. Simmons, had to google him, then I recognized his face. I don't understand how such people are important for a video game, I do not care the slightest wether a celebrity is in or not or in some way involved, but most seem to like that.
