I think complaints that Vaarsuvius is ruining O-Chul's plans are a little overblown. O-Chul has been working on the MitD for a while now, and he probably has a while still to go to get results. I don't think the Monster was right on the verge of turning on Xykon or anything. If Vaarsuvius can win, great. If Vaarsuvius loses, I don't think it particularly undercuts the work O-Chul has been doing.
