Which we just have his word for when he's attempting to cause Sayaka to despair. He gets why humans consider it unethical, he just doesn't care. If he could dodge contracts and get the same or better payment, I think he would.
Given that he seldom explains everything when asking young teen girls to commit to a short lifespan as a magical girl, I'd argue those contracts were not made in good faith from the beginning.
He won't violate them from his own internal logic- at least when asked about it. That doesn't mean anyone else will necessarily agree with that logic or that it'll be at all acceptable as an outcome to us.
No, the worst case scenario is him using this as a conversational opening to talk to everyone, hint to Madoka that someone's dying and we've asked him for help, and generally giving us dangerous misinformation.
To which we explicitly tell Madoka that we have it covered and are making progress, and we have access to a healer. If she still wants to contract, we tell Madoka what will happen if she contracts, as in planet-destroying Witch.
I'd rather talk to it as little as possible, forever, and that involves not tying ourselves down to a conversation we shouldn't want to have.
So we should just get rid of him rather than needlessly exposing ourselves to a headache for no benefit.
I will gladly vote for a less confrontational way of getting Kyubey out of the room, but being openly aggressive toward him is asking for problems later.
Kyubey is literally incapable of feeling anger. There's no reason to worry about it being "mad".
See that's where we disagree
But doing that, will make him question why we are openly hostile to him, that could link us to Homura, from there he could try to investigate Homura, find out about her being a time traveler, then drop the Potentialbomb against Homura, like Canon.
We don't give him a conversational opening and he'll back off for the moment. It's just how he operates.
He's the enemy. THE enemy of PMAS, really. I don't see that working out for us.
