text: how does achilles rage lead to the greeks downfall in the illiad?   achilles rushes into the temple of apollo and kills trollius on the alter, pissing off the god.  later, a weapong guided by apollo kills achilles, with either (depending on the story) by a knife stab in the back or an arrow to his heel from paris.  the irony and divine insult being that paris (or the assassin) is a coward killing the fearless achilles.
