Obviously, the solution to this debate is to be found in the following quote:
"Good. Bad. I'm the one with the shotgun."
-- Ash, "Army of Darkness"
Also remember that history books are written by the victors, and that nine times out of ten, it was the better armed side that won -- which is not necessarily the good side. Istanbul is right about evil's lack of predictability providing a tactical advantage. However, many evil things have been done in the name of "good".
Let's see if we can name a few...
The Salem witch-burnings -- superstitions and mob mentality are powerful beasts...
The Inquisition -- fear of the loss of power by a certain church allowed all sorts of brutality and torturing in the name of "good".
The Crusades -- let's see if I can't sum the Crusades up... convert or die. Come to think of it, that is the jist of most holy wars.
Also, villians are rarely villians in their own eyes. In fact, they may believe that what they are doing is for the good of humanity. Though I don't agree with Nazi teachings, or any of that "one color is better than another" bullshit, the hardcore members of those groups honestly believe that what they do is for the good of "humanity". So to them, my good (color-blind humanity) is evil of the worst sort.
