Kratos vs The Norse Pantheon

[warty goblin]

In Greek mythology, I'm pretty sure that harming the fates is something that is legitimately impossible, and something that even the gods and titans were incapable of, making killing them on the same scale as killing the fates in North Mythology: It shouldn't be possible, at all.

Killing the Fates in Greek mythology may or may not be possible. Thwarting them however, if you are powerful enough, is. Zeus makes it abundantly clear in the Iliad that if he so chose, he could save Sarpedon and Hektor, even though both are fated to die at Troy. He decides not too since apparently the other gods don't like it when he starts screwing with Fate, but he clearly is capable of doing so.

Interestingly, Thetis never asks, and Zeus never considers, saving Achilles.
