From the Light Within:
Player: Zaros has returned in my time. He's corporeal again.
Guthix: 'Zaros'... I have heard this name before. Seren spoke of him. I am not aware of his presence. If he was here, he departed long before I awoke.
Player: He was slain by one of the gods you banished, but has since returned.
Guthix: To return from death is an unnatural act requiring great power. Be wary of this god, adventurer, such power rarely comes without a cost.
Granted Zaros really didn't die, but Guthix definitely wouldn't have liked the 2nd age Zaros. Considering, you know, Guthix wasn't a fan of gods interacting with mortals, and Zaros was very hands on with mortals at the time.
It's also fairly likely that Guthix wouldn't like Zaros as he is now even if we assume that Zaros is being 100% transparent and honest because Guthix didn't like worship of gods in general (even when done voluntarily without duress) and even worked to cease worship of himself at times.
