Note: I am not a psychologist, although my other half often suggests I'm mental (and possibly in need of one)!
What sort of person are you, though?
Two sides fight a battle. One side wins. The is scrubbed out completely. Did the good guys win?
Optimist: The good guys won, because they deserved to.
Pessimist: Everybody lost.
Realist: History is written by the winner - so of course they're the good guys (eventually).
Feel free to make up and add your own types! :)
