This goes further toward my point that neither Wrathion nor Sabellian would make for a good Aspect - whether it's being brash and misguided, or being a misanthropic prick, you don't want either of these personality types amplified by feeding them untold Titanic power.
I understand the desire for conflict in the story of a game, but I don't agree that the potential for conflict should come at the expense of either internal consistency or the suspension of common sense. I don't want an obviously bad choice to be made solely because the outcome of living through it would be "fun," this detracts from the narrative in the longer term, and goes more toward ruining immersion than it any short-term narrative gains it might provide. Sure, either Wrathion or Sabellian would be the best choice if your sole interest was maximum carnage - but the decision to anoint either of them would be dumb, especially if it's willingly done by the other Aspects or by the mandate of the Titans. Now if Wrathion or Sabellian were to somehow "steal" the mantle of Aspectral power you'd have a different kind of story, one that I could get behind - but willingly choosing either of them at this point? It's a bad decision all around, both on the Watsonian and Doylist levels.
