The interview with Call of Juarez: Bound in Blood writer Haris Orkin on The Game Reviews talks with Haris Orkin, writer on the wild west shooter prequel. The conversation covers possible controversy over issues explored in the game, as it touches on "racism, slavery and the oppression of Native Americans and Mexicans in south Texas." Here's a bit:

I’ve been reading some of the forums. Some people - not very many - are concerned that the playable characters are on the side of the confederacy. Some people simplistically believe that everyone who fought on the side of the south was evil. The truth is, the causes of that war were very complex. There were northerners involved in the slave trade and southerners who didn’t believe in slavery. When the war started it was more about state’s rights versus federal control. The truth is, most of the soldiers fighting for the Confederacy were not slaveholders. Maybe 20 percent had slaves. Atrocities were committed on both sides. Many of the actual outlaws of the time were former confederate soldiers; Jesse James and his brothers, the Youngers. Archie Clement. So the McCalls were based somewhat on those actual outlaws. Confederate soldiers who suffered the brutality of war and lost everything they had.
