Oh my ... few days i dont check, and this is what you create ... well, im too lazy to read it whole, but there is one thing i just need to react on:
Please remember, playing evil is NOT just murdering everyone mindlessly. Playing evil is ruling by fear, power and authority. Power and authority, exactly what we get to read in our dialogues when we can use our powers. But this is not reflected ingame at all!
This is core of our problem ...
Everyone here seem to be sure that they are the only one who discovered and understanded the "only right way" of being evil, and everyone else is just doing it wrong ... but what if we all are right, just different?

When you look at this game as whole, you can see that Larian took it in best way they could, they just give us options ... and is up to us what character we want to play.
Do you want murdering everyone midlessly? You can.
Do you want to rule by fear, power and autority? I believe you will be able when story will be complete. (i know that you cannot yet, but if you expect to be king of the universe after butchering few refugees that no one cares about .... i gues there is different misstake)
