16. Major Marquis Warren
The Hateful Eight – 8 Kills
Warren is also a bounty hunter, except he’s a little more violent than the previous guy. When we’re introduced to him, he’s already killed three bounties and is in the process of transporting them to town.

Later, when everyone is trapped inside during the blizzard, he takes out Smithers, Mobray, Bob, Jody & Daisy Domergue. Not a bad day for gunfighting.
