In Red Dead Redemption, can I kill people near the end when coming out of the barn?

When I come out of the barn at the very end, for my very last stand, can I kill any of the main culprits who I'd like to exact revenge on?

Solution 1:

As far as I know there is no way you could kill any main character in the last stand as the only ones showing there are generic army characters.

Solution 2:

To disagree with some of the other posters, The Last Enemy That Shall Be Destroyed mission on the Red Dead Redemption Wiki offers the following as a possibility.

Even though the player can shoot Edgar Ross and Archer Fordham dead in the final Dead Eye moment, Ross will still be alive in the following cutscene.

Solution 3:

Well you can't kill any of them straight away, but if you keep playing as Jack you will eventually duel and kill the main federal agent badguy (you need to talk to the agent at the station in Blackwater, not on the map).
