Shaka is the personification of `Good´ (Japanese Buddah Shaka Nyorai), while Lucci as the personification of `Evil´ is a short form for Lucifer.
You just have to take Lucci's head and put it on Shaka's body- it fits perfectly in every panel (body language, eloquent speech, thinking, etc.) I have written since early spring that both mirror each other but everyone just disregards it as pure theory, when it's actual analysis.
