Agents of S.H.I.E.L.D., Season 5

Fitz:
We were trying to get ahead of the problem.

Mack:
By having Yo-Yo execute a kid?

Fitz:
Things got messy, but, I mean, it was the only way that Y-Yo...

Mack:
When does killing become the only way? We're S.H.I.E.L.D. Aren't we 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 the 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 prophecies. It's following the Good Word and doing the right thing every time, simple as that.

Fitz:
No. Not always, 'cause there are lots of instances in history where, where it was necessary to sacrifice the few in order to save the lives of many.

Mack:
'Course you'd say that.

Fitz:
Ruby was dangerous and it got complicated and that is just the way it was. So I'm sorry if that doesn't fit whatever narrative that you've built for yourself.

Mack:
You need to look inside yourself and figure out what kind of man you want to be. 'Cause lately, what you've been, it needs fixing.
