The only way Lee could have killed federal soldiers would be if he was in a war with them. The only way he could have met them in war was if the two sides came together. Lee was in Virginia through the first 2 years of the war. That would mean that the federal soldiers had to ALSO be in Virginia. What were they doing in Virginia? Why waging war! So who was responsible for their deaths? Lee? No, their own government and commanders. If they'd stayed home, they would never have died but once they chose to commit treason by making war against the State of Virginia - and the rest of the Southern States - then that was their fault, not Lee's. Have you read about Sherman's crimes against women and children? Probably not..... it would suit your liberal agenda.
