Heroes who have killed

[Gorblax]

I’m trying to put together a list of heroes and anti-heroes who have killed before. There are obvious ones, like Red Hood and Vigilante. But then there are others:

Superman, who killed General Zod and company in the pocket universe of John Byrne’s run.
Wonder Woman, who killed Maxwell Lord during Infinite Crisis.
Barry Allen, who killed Reverse Flash before Crisis on Infinite Earths.
Green Arrow, who spent time in an ashram after accidentally fatally shooting a criminal.
Cassandra Cain, who killed one target for her father before realizing what she had done and running away. She also once killed Lady Shiva, but left her suspended over a Lazarus Pit. Then there was all that OYL stuff.
Batman, who killed Darkseid in Final Crisis.

What else you got?

In Tom King’s Batman run, Swamp Thing killed the man who murdered his father.

[Gorblax]

Morpheus, Dream of the Endless, killed his son.

[Gorblax]

Frankenstein and The Bride both had to kill their own child, as well.

[Gorblax]

Helena Bertinelli (Cry for Blood), Rose Wilson (Various), Connor Hawke (Dragon’s Blood), Mia Dearden (around the time she became Speedy). Killer Frost, naturally (now just Frost).

[Trey Strain]

if the dead person comes back to life, does that count as being killed?

[Gorblax]

if the dead person comes back to life, does that count as being killed?

Yeah, that’s still murder.

[Trey Strain]

Yeah, that’s still murder.

I dunno. The super-heroes have seen enough dead people come back to life that they might suspect that their killing a villain is probably just an empty gesture.

Guy Gardner is one of quite a few characters who have "killed" Major Force.

[Jody Garland]

It was left up for interpretation, but Jason Todd likely killed diplomat Felipe Garzonas in Batman #424.

I can only think of two more that haven't been mentioned:

In Legion of Super Heroes (Pre Crisis), Queen Projectra killed Nemesis Kid

In JLA/JLE Breakdowns, Silver Sorceress killed Dreamslayer right before she died herself

[Trey Strain]

Guy "killed" Major Force because Major Force had "killed" Arisia.

[Restingvoice]

It... doesn't matter if the people are revived or not. When they killed them, they didn't know they're going to be revived. If they fully intend for the person to be permanently deceased, then it's murder.

Red Hood killed mobs
Damian killed The Spook, Otto Netz, and Nobody
Kathy Kane the original Batwoman killed Talia

Are we counting accidental killing or intentional murder only?

[Jody Garland]

First post has Green Arrow accidentally killing a guy, and I don't think Barry meant to kill the Reverse Flash back in the day, so accidental killings should be fine.

[Ra-El]

Green Arrow killed a bunch of people, on Lemire's run Oliver was burning people alive.

Tommy Monaghan a.k.a. Hitman (not a surprise)

Superman killed Doomsday.

I don't recall, but I'm pretty sure that Constantine have killed someone, or at least send them to hell or something.

[Hilden B. Lade]

Jonah Hex's probably got a body count the size of at least Texas, California, and Alaska put together.

Constantine directly killed The Family Man. Others generally go out by indirect means... having a buddy do the dirty part, trick them into stepping into heaven's turf, etc. if that counts. And of course, a pivotal moment in his backstory involves accidentally condemning an innocent to hell.

Animal Man killed the people responsible for his family's death in Morrison's run.

Lobo (assuming he fits the anti-hero criteria) did kill Santa Claus among others...

The Omega Men in King's run.
