you think a man who led an insurrection against the united states is more hero than villain. a war that cost more US lives than any other war the US has ever fought. no matter his reasoning he is guilty of the deaths of thousands of americans. you can call him a hero for doing that if you wish...but pardon me if i disagree with you on that point.
Here's some assorted quotes from his wikipedia page:
"When Virginia declared its secession from the Union in April 1861, Lee chose to follow his home state, despite his desire for the country to remain intact and an offer of a senior Union command."
"Lee rejected the proposal of a sustained insurgency against the Union and called for reconciliation between the two sides."
"In 1865, after the war, Lee was paroled and signed an oath of allegiance, asking to have his citizenship of the United States restored."
"in that position, he supported reconciliation between North and South.[9] Lee accepted "the extinction of slavery" provided for by the Thirteenth Amendment, but publicly opposed racial equality and granting African Americans the right to vote and other political rights."
"Lee opposed the construction of public memorials to Confederate rebellion on the grounds that they would prevent the healing of wounds inflicted during the war.[9] Nevertheless, after his death, Lee became an icon used by promoters of "Lost Cause" mythology, who sought to romanticize the Confederate cause and strengthen white supremacy in the South."
"Lee's objection to secession was ultimately outweighed by a sense of personal honor, reservations about the legitimacy of a strife-ridden "Union that can only be maintained by swords and bayonets", and duty to defend his native Virginia if attacked.[108] He was asked while leaving Texas by a lieutenant if he intended to fight for the Confederacy or the Union, to which Lee replied, "I shall never bear arms against the Union, but it may be necessary for me to carry a musket in the defense of my native state, Virginia, in which case I shall not prove recreant to my duty"."
"Lee resisted calls by some officers to reject surrender and allow small units to melt away into the mountains, setting up a lengthy guerrilla war. He insisted the war was over and energetically campaigned for inter-sectional reconciliation. "So far from engaging in a war to perpetuate slavery, I am rejoiced that slavery is abolished. I believe it will be greatly for the interests of the South.""
Seems like a quite morally ambiguous person who can't simply be dismissed so easily as all hero or all villain.
