Killing like that should never feel good!
Jonathan: That was incredible.
Clary: You killed a man, Jonathan. A Shadowhunter.
Jonathan: And I did it for you. Seeing him in your arms like that ... so vulnerable. It wasn’t like any kill I’d done before. Clary, it felt so good! You make me good!
Clary: That’s not what good is, Jonathan. Killing like that should never feel good!
