Natasha: You understand why this place has to be obliterated?
Clint: What about Krylenko’s wife and kid? Don’t they deserve to know why he died?
Natasha: Who do you think told Russian intelligence where he was hiding?

Clint killing Bruce Banner in Civil War II #3 was almost the natural endpoint of several years of Brian Michael Bendis Clint stories, where he was killed, resurrected, and then forced to cosplay a ninja, all of which seemed to lead to his contemplating murder. Outside of these Bendis plotlines, though, Clint has always been queasy about killing.

In this story, Clint investigates a murder that leads him to Natasha. It turns out that his local deli owner was actually a genocidal war criminal who still had control of illegal sarin gas weapons. Natasha was hired by the Russian government to kill him in order to prevent another genocide— which was too morally complicated for Clint’s comfort.

The situation doesn’t quite repeat in Civil War II #3, but it rhymes: the idea of killing as preemtive self-defense not quite being murder, and the twist of the victims themselves being complicit. Clint was predictably Not Okay with Natasha’s actions here, which makes it interesting to think how Natasha would react to Clint’s current predicament. I don’t think she’d relish the role reversal. Part of the reason Natasha keeps doing dubious things for the Avengers is so other people do not have to. At the end of her last series she had actually determined not to do that anymore, to stop taking on every moral cost. Perhaps she would see Clint’s change as an inevitable result of that decision, instead of many years of Bendis plotlines. It wouldn’t be logical but Natasha has a lot of guilt where Clint is concerned already.

I doubt we’ll see this actually touched on anywhere, but the Mockingbird book is dealing with similar issues from Bobbi’s perspective, since their relationship has also suffered lots of obstacles related to when to kill and when to let things die. Basically, everyone should be reading Mockingbird.

From Hawkeye #8, by Fabian Nicieza and Joe Bennett.

Bobbi: If I did expose you to repeated low doses of an experimental neurotoxin during our marriage it was only to inoculate you. And because I didn’t want to use it myself until I knew it worked.
Clint: You poisoned me?

Clint: Natasha, please tell me you’re not experimenting with those old Russian poisons again.
Natasha: I only paralyzed you for a week, Clint. You need to let that go.

From Mockingbird #4 by Chelsea Cain and Kate Niemczyk, & Astonishing X-men #62 by Marjorie Liu and Gabriel Hernandez Walta.

Hercules: Still the mortals stop to stare at me! Is my appearance somehow amiss?
Wanda: On the contrary, Hercules! As the slogan says, you must be doing something right!
Clint: Well, pretty lady, it looks like you get stuck with nothing but a plain-clothes archer!
Natasha: I shall try to survive, my darling… as long as you keep paying me compliments!

From Avengers #46, by Roy Thomas and John Buscema.

Clint: Up your horns, fella! I’m not leavin’ without ‘Tasha!
Matt: Keep wishing, Avenger! The Widow’s not up for grabs today!
Natasha: That’s enough— both of you!! I go where I please— with whom I please!
Clint: That’s tellin’ him, Spider Lady!
Matt: Hawkeye, do me a favor: shut up!
Natasha: I wish both of you noble, selfless defenders of the good would start acting the part. Meaning, can we go inside and discuss this like civilized human beings?

Ship wars, c. 1973.

From Daredevil and the Black Widow #99, by Steve Gerber and Sam Kweskin.

Natasha: Look at the state of you. Who was your date last night? Did she bring a threshing machine with her?
Clint: Nat, c’mon, don’t act like you’re my mom…
Natasha: Clint, we both know I couldn’t possibly be your mother. You certainly never acted like I was.

From Avengers: Endless Wartime by Warren Ellis and Mike McKone.
