Crasus and his respect for Spartacus

Just a little thing I noticed that I do not believe people really touched on. Crasus knew how important Spartacus was and the effect it would have on people if he took him as a war trophy to be paraded around with. Instead he was going to give Spartacus an honorable death and end his life. He knew Spartacus got the best of him and did not taunt him like Ceasar did Gannicus after being embarrassed so many times. It made me respect the character all the bit more and really helped me stomach the bitter sweet ending
