Mack: When does killing become the only way? We’re SHIELD. We’re supposed to be better than that. None of this would’ve happened if you would’ve just said this “invincible” nonsense wasn’t real. But instead you and Simmons lit a match and now Yo-Yo’s responsible for a girl’s death! Fitz: I’m sorry, Mack. I really am. But it’s not that simple. Mack: Simple? Is how you live a good life. Not with your theories or prophesies. It’s following the Good Word and doing the right thing every time. Simple as that. Fitz: No. Not always, ‘cause there’s lots of instances in history where it was necessary to sacrifice the few in order to save the lives of many.
