In keeping with the hypothetical scenario of this thread,my opinion is that Fredo would not have been killed.
With Vito alive, Mike would never have given the order.. I think an interesting question is what Fredo's status would have become under those circumstances.
Assuming that Mike would be compelled to follow Vito's advice in this matter,what would be the outcome?
Would Fredo be permanently banished from the family,or punished in some other way. Would Vito forgive him since Mike survived the hit?
Naturally Fredo would be finished as a Mob guy,even the wannabe one that he was.
And just to stir it up,would Fredo have gone along with Ola and Roth in the first place?
Since his main beef was being relegated to errand boy status,would he have gone to Vito first to ask for more responsibility?
Just throwing out some random ideas.
Any thoughts?
