Zeus's Protection Order on Herc

Oh, in case you didn't know, Zeus has placed his protection on Hercules. In case you forget, these lovely gods and goddesses would love to remind you:

1.01 Treasure of Zeus

Strife: No god can destroy Hercules without being fried forever by Zeus. Am I right, or am I right?
Ares: You're half-right. Obviously we can't attack him directly. But sometimes a little strife can lead to a major catastrophe.

1.03 What a Crockery

Ares: Mother, I thought you knew. I really had no idea you cared so much about the chalice.

Hera: I want the perpetrator!
Ares: Dead? No can do. It was Hercules-- and you know how Zeus feels about little bro. Daddy's put his protection on him-- preventing us gods from killing him.
Hera: Hercules?
Ares: What? Am I missing something here?
Hera: Zeus made a promise to me when he made us that chalice. Anyone who takes it from its rightful place-- is condemned to death.

Ares: Then by Zeus' own words-- his protection of Hercules is off.

Hercules: What do you want?! If you're here for the chalice, just take it and leave us alone!
Ares: What I want is to see you suffer. When you grabbed Hera's chalice, you lost Daddy's protection, and now, I can destroy you.
