>There's a very good reason that good ol' Doctor Vahlen was the face of the baddies in it: she's that very special combination of ivory tower arrogant, annoyingly officious, and scientifically sinister that eventually results in bad science.
Had you seen the plot of XCOM 2 DLC? Only thing that prevented Vahlen from being that was Great Commandy One and his psionic abilities. After he got captured, she got into remission and started to do things to aliens. Bad things. Things that caused everyone to ask her "Why? What's the point?" Things that break game mechanic. Things like Viper King. Or Berserker Muton Queen. Or Archon King.
