I wrote a whole post about Murder Cap.

I mean, the entire opening scene for the Winter Soldier is Cap straight up murdering a number of dudes.
Let's take a look at the replay.
1. Choke hold. Nice Guy Cap.
2. Hit in the chest by shield. Broken sternum, collapsed lungs?
Dead or dying.
3. Hit in the gut or crotch by the shield. Severe internal bleeding. Passed right out.
Probably dead.
3. Kicked! Definitely a broken spine, thrown off the ship.
Likely dead.
4. Punched! You get to live.
5. Kicked! You get to live.
6. Thrown offboard at sea.
Slow, slow death at best.
7. Punched.
8. Kicked. Also guy #10, stabbed through the hand and then kicked in the face so hard he's knocked out. Concussion?
9. Jujitsu takedown.
11. Shield face first. Many teeth gone, probably a broken jaw. Assuming Cap didn't shake his brain around his skull, this guy gets to live!
12. Kicked by Cap in the gut. Boot isn't as hard as shield. Huzzah restraint!
13 & 14. These two take the shield to the gut and face. I'm going to say they survived.
15. Cap does a goddamn piroutte to throw the shield hard enough to hit this dude in the chest and bounce back to him.
Reasonably sure he's dead.
16. Two knees to the head. Concussion. Maybe alive!
17. Jujitsu takedown!
18. Shield face first. Severe blunt force trauma. Probably a concussion.
Maybe dead.
That's six dudes that are dead. Possibly more depending on how hard Cap punched or kicked them and that's being generous.
