@Rayodino They were hiding, therefore he should try to find out about them? In real life, people don't post their personal information everywhere. That means we should try to find all their personal info!
He literally violated the rules. He even admits it. You're directly wrong on this.
Your third point isn't a point. Like, why does it matter if he tells them about the elixer or not? This is irrelevant. The point was that he lied and then admitted to lying. That means he is untrustworthy. He is suspicious. He admitted to lying. They have no reason to trust him.
I didn't actually say that their repeated torture and healing is justified. I didn't say that. Look above. That is absolutely not what I said.
And what, are you really saying him killing them all would be justified? That's something you are literally saying. Ignore the fact that he is suspicious as hell and violating the rules. He should kill them even though he was doing bad things.
