@darklordoftech, I agree with your point of view. However, there are those who do not believe in absolutes such as good and evil or that one must triumph over the other. Such individuals can take from Sidious' words that he is good from his point of view and if you adopt that point of view then you see the Jedi as evil (like Anakin did at Mustafar, "From my point of view, the Jedi are evil!" Sorry I couldn't help it, I quoted that line often during ROTS days). I think Lucas wants us to ultimately see The Emperor as evil, but if you take Yin and Yang and other eastern beliefs like Zoroastrianism into account (all of which Lucas was influenced by) then you can interpret Palpatine's words and point of view differently. To be clear, I am merely sharing as Obi-Wan says, "from a certain point of view."
