As a note, any large non piercing impact to a wakandan cannot be assumed to be lethal, as they sometimes weave Vibranium into their clothes (as confirmed through some possibly unreliable exposition from Klaw, but also from the comics and .. you know.. just watching the movie). Estimating impact death is essentially impossible.
9:59 Guy gets thrown into a truck really hard
10:50 Okoye stabs a guy with her spear (other take downs in this sequence would not be enough for a confirmed kill)
17:26 Klaw and cohorts shoot 4 guards
47:31 Nakia shoots 2 of Klaw’s guys
47:50 Okoye stabs one
48:04 Klaw shoots an agent
50:14 Shuri runs over a Klaw flunkie

58:49 Killmonger shoots 2 operatives
1:02:32 Killmonger shoots a Klaw mercenary
1:02:47 Then he shoots his girlfriend
1:03:48 Killmonger shoots Klaw
1:06:44 Killmonger’s dad is killed by T’Chaka in flashback
1:20:45 Killmonger stabs my favorite priest and secret samurai
1:42:20 A ship is destroyed and we can safely assume that at least a pilot is killed and since all the other ships have at least 2 people in them as seen in later footage, we will assume 2 dead
1:44:33 Another ship destroyed, so 2 more
1:46:11 Killmonger kills a royal guard
1:47:56 Ross shoots down an aircraft (2)
1:53:32 Ross takes down 2 more ships (4)
1:53:55 Ross takes down the last ship (2)
1:58:18 Killmonger dies
Total: 37
This kill count comes to a much higher total, but they count quite a few physical interactions as kills that are just not likely to be.
Carnage Count makes the same choice and thus also has a higher count.
And not to sound like a broken record, but Every Death makes this exact same choice.
