I suggest you read that page again with all the crimes. Sora isn't just manipulating people just to get the sky regalia. He is doing it to control the AT world.
and whats so bad about being manipulative? that doesnt make you evil... it just shows that you have the will to gain what you want do what you need to do to get it plain and simple also it does seem sora is the "A" person which makes me like him even more personally shows hes actually got some real motivation to get what he wants unlike kilik who is whiney bitchy and annoying (imo) and besides the thing im interested in is why is it so bad to manipulate others to get what you want people do it all the time and most the time they arent considered evil unless you read it in a story then its like OMG THIS PERSON IS BAD! lol
