some spoilers included so dont read if u dont want to:rolleyes:
well Emperor is considered ultimate bad guy in old rep times, but what if...
what if he actually wants to perserve life in galaxy through destroying it (reapers much)
in JK story he talks not only about destroying all life, but creating life. about other galaxies, it kinda smells like he has to do it to become stronger - like he was planning something more than just ascending into greatness. he understands concept of dark and light side as equally imporant, he even said something that sounds like part of jedi code "there is only the force" - if i recall correctly.
but when it comes to SOR we don't rly get much new info. we know wrath had vision of destruction, and EMP has plans for him. from SI story we know there are very advanced spieces in galaxy who posses knowledge of prolonging lifespan to almost immortality - thru science, not the force - which means they are more advanced and should be considered huge threat
and dont forget vicious yhuuzhan vongs
i mean bioware left so many doors open - that we can't rly say what is going to happen really.
