Would want to is much less important than "Can he?" If it makes sense, go ahead. And I think it probably does make sense.
Edge, even he knew he was. He just considered it necessary. It didn't make him less badass, though.
The church is actually NOT in charge of overseeing this one. The mage's association did a table flip since before so they actually went and sent their own in (If Phantom's overseer is more neutral, I'll leave it at one. If the overseer is more lopsided, I'll add another mostly inactive one just to act as the representation for the "other side" of the mage's association). So they won't flip out that hard over a bunch of human killing. If you killed enough, maybe but they'd take a lot more bs and wanton slaughter than a church overseer. Yes, if that happens, the command spell reward may also happen.
If someone's pretty screwed, then they'd better think about how to get unscrewed or prepare themselves to get squished. Whether they run, bargain, die like a dog, etc is none of my business but I suggest at least trying to not die like a dog.
