That scene in my own opinion is the most foreshadowing/ symbolic of the whole movie. I mean he knew what he was doing was wrong (the crying) but yet he still did it, and dug deeper into the dark side. The crying shows he still has human compassion whether it be a minimal amount, its still there. It foreshadows his last moments when he felt compassion for his son and killed the emperor. Oh and to answer your question yes i did see him cry. lol
