i heard in R’ Hutner’s name that how could it be Eisav was a rasha from the womb? (if he was considered a yisrael mumar, that means potentially he could have been a tzaddik. yet we see that from the womb he’s struggling to get out when Rivka passes by bais avoda zara. where’s his bechira?)
he answers that Eisav was not a rasha from the womb, nobody is. in fact, Eisav wanted to go and destroy the avoda zara. that was his machlokes with yaakov, to actively destroy avoda zara or to just learn.
then he was born and the rest, as they say, is history. 🙂 heard from R’ Dovid Heber in Baltimore
