Well, there may have been a couple of troopers who didn't deserve it but Custer sure had it coming. To ride into a town, where families were sleeping and massacre every one they could with NO justification is an act that calls for justification. We won't go into the horrible things that were done to those victims. Hitler may have studied Custer for all we know.
No where in the story does any of those atrocities fit into our image of an American soldier but it happened.
