It ' s exactly as you say . They can ' t leave him alive because someone could flip a switch somewhere and turn him into a courser in power armor instantly . The same can be said for all synths , regardless of how sentient they are . Danse also knows too much about them to be left as a loose end . Ghouls used to be human and are still essentially prewar people , but every single one of them has a countdown running until they go feral and start eating faces . Exterminating them wholesale the way they do with synths is a bit much , but quarantining them and making sure they don ' t endanger people is something that needs to be done . <| sep |> Would definitely be interested in this . The only issue I can see is any mod that affects shouts would need a patch . Including perk overhauls , new shouts , changing shout intensity , etc . But it would be nice to have separate cooldowns again .
