Poor Fredo copped it from everyone - Vito, Carmela, Sonny, Michael, Greene, Deanna

Fredo was an unusual problem indeed and no real viable solution even face saving - Don or ?

Fredo was not Don material but then again neither was Sonny as bad a Don as Sonny was, Sonny interestingly still would have been Don if he was not killed

Wonder whether there are any older brother stepped over situation and if so how it panned out, in real life? Thanks
