In the first version of the game Civilization, each character had an "aggression" rating, stored as an 8-bit integer. The programmers of the game gave one of the characters, Gandhi, an initial aggression rating of 1, the lowest of any character in the game. The game also had logic such that, once a character "adopted democracy," the character's aggression rating would decrease by 2. However, the game had a bug whereby Gandhi would become extremely aggressive, with an aggression rating of 255, if he adopted democracy. What might explain why Gandhi suddenly became so aggressive in the game
