Sacrificing people will not release the Nogitsune from the glass jar. If they wanted the Nogitsune to be freed then all they need to do is find that jar and unscrew the lid.

As for Theo wanting Void Stiles, he clearly hadn't thought about the ramifications. The Nogitsune is chaotic evil. It does what it wants, when it wants and for no other purpose than because it can. It thrives when creating chaos and being evil. A being like that would play games with Theo and make the Dread Doctors seem tame in comparison. At least with the DDs, we know they have a finite time line, a goal and purpose beyond just being evil.
