Another interesting thing about this interview is her focus on morality.

In particular, her claim that Vito's negative reaction upon learning that Michael killed McCluskey and Sollozzo was based on the damage to Michael's soul, rather than the ruination of Vito's plan for "Senator Corleone. Governor Corleone."

I never thought about it that way, but I think she may be right. Tom Hanks's mafia hitman character in "Road to Perdition" is motivated by a similar desire to keep the soul of his son (also Michael, IIRC)clean.

I'm less sure that I agree with her assertion that Vito spends the whole movie searching for redemption. His "I don't apologize" line belies that claim.

"A man in my position cannot afford to be made to look ridiculous!"
