re: #463 Obdicut
Apparently none of the soldiers in the Civil War ever willingly shot each other. It was all terribly unwilling. Somehow.
Given the significant number of muskets recovered from battlefields showing multiple unfired charges (soldiers pretending to load, aim, and fire) and the surprisingly light casualties in most engagements), yes, most men were unwilling to kill.
Sugest you look into the USMC studies on the subject. Most normal people cannot stomach the thought of killing another person.
