Very Unstrusworthy

[Sheogorath]

I know how ya feel. I only declared war once in my Turks game and somehow got 'Very Untrustworthy' at the end of the day, even though the stupid Byzantines had already attacked me twice (once as their vassal, no less.)
Pretty soon that was followed up by a crusade, so I ended up with 'Abysmal' relations with all the Catholics, and Egypt was already attacking me...
So I just said, "Fine, screw the lot of you, I'll kill you all and create foot rests out of your skin."
And thats the story of how I invented the Ottoman.

yes murdering your defenseless prisoners gives a bad world reptuation, you either gotta be a saint in this game or a devil, if you want to be trustworty, let the enemies troops go, not only do you get chivalrous bonuses but the next time you fight that army they will have less men, if you killed the lot of them the comp would replace them with fresh units.
