What did you expect?
Athene and Ares were in a win-win situation when they went to the Trojan War ... Ares was on the side of the Trojans and Athene fought for the Achaean Greeks ... no matter who won or lost the war, there would be enough blood and gore to satisfy even the most gruesome appetite.
The next time you see a vulture in the sky, try to remember that they might be one of the Immortals out for a snack ... try not to disappoint them.
