Well summed up! Your points of manevolence and true even are justified, and I believe quite true.
But now (mwa ha ha)...
Are those manevolent beings manevolent because they are born that way, or because they choose to be? Can something be manevolent from birth?? (Forget Evil, lets just say it comes from general manevolence) And, how does Evil develop from manevolence, or can something be truly evil from birth rather than just midly manevolent?
