A very strict and holistic approach is the fact that the world power doesn't reside in any object or "virtual" institutation but rather in each and everyone of us. We can choose to delegate power to multiple organizations such as government which therefore make the power that be, being as of today's world, being quite well centralized.
Evil or some kind of chaos (except some chaos destroying chaos), in fact the outer dark, make us being devided and is the cause to human suffering and the main limitation to our freedom which doesn't appear "evident" because it is difficult to see how our personal suffering are (as a whole) caused by the same entities which cause other human suffering.
This limitation in our freedom, well being and evolution can be because of a lack of knowledge, previous manipulation and too much of indoviduality, but it is also the same thing which shape our evolution trough difficulties and constraints.
But too much "evil" is counter productive in terms of "evolution shaping".
A perception shift is occuring since the information revolution age (since the internet) which permit us to connect to each other and share knowledge. This effect has took tremendeous and awesome proportion theses recents years and more specifically months.
Maybe this world is another planet's hell or maybe it simply is what we are doing with it.
But one thing is sure, the world is changing!
