Ὁ οὖν Ζεὺς καὶ οἱ ἄλλοι θεοὶ ἐβουλεύοντο, ὅ τι χρὴ αὐτοὺς ποιῆσαι, καὶ ἠπόρουν· οὔτε γὰρ ὅπως ἀποκτείναιεν εἶχον καὶ ὥσπερ τοὺς γίγαντας κεραυνώσαντες τὸ γένος ἀφανίσαιεν —αἱ τιμαὶ γὰρ αὐτοῖς καὶ ἱερὰ τὰ παρὰ τῶν ἀνθρώπων ἠφανίζετο— οὔθ᾽ ὅπως ἐῷεν ἀσελγαίνειν. I understand why
ἀποκτείναιεν is in the opt : it replaced coniunctivus deliber. , but why ἀφανίσαιεν is also in the opt? By assimilation? Or is it part of implied oratio obliqua in which ind ao of oratio recta shifted to opt.

In addition I think that καὶ ὥσπερ here means something like ‘and especially as’ or ‘moreover as’

ok, its opt replacing con delib as the previous one, because the word order is: οὔτε εἶχον ὅπως ἀποκτείναιεν καὶ ἀφανίσαιεν ὥσπερ τοὺς γίγαντας κεραυνώσαντες τὸ γένος
