The hope crashes into reality and people get hurt.
Suffering is the fuel in the engine of civilization."

Jedi do not fight for peace. That's only a slogan, and is as misleading as slogans always are. Jedi fight for civilization, because only civilization creates peace. We fight for justice because justice is the fundamental bedrock of civilization: an unjust civilization is built upon sand. It does not long survive a storm.
