I have a feeling that "Achilles" is as much a golem as Diana is (i.e. not the undead come back to life) even if he is somehow connected to the Achilles of lore. This would further the connections between "the Olympian" and "Wonder Woman" if indeed Gail is trying to make Achilles the male mirror image of Diana. So far he hasn't been portrayed as a bad guy. It took Diana decades to rid herself of Zeus, give Achilles time (that is if he's meant to last out this arc/s which I somewhat doubt).
