Ref: thread Tom and Fredo may be of interest regarding Tom's shortcomings

Than again, Michael had his own shortcomings and failings as well among others,

  • [also Don Tommasino] underestimating Fabrizio
  • falling for 'spin doctor' Ola's 'propaganda' about Tropigala that Michael can move Klingman out and their friend [Roth] in Miami will go along [in spte of Ola bringing an orange! from Miami]
  • underestimating Roth
  • [also Vito] underestimating Fredo
  • underestimating the Rosato brothers that they would “settle these troubles” with Pentangeli
  • underestimating Kay [Kay overestimating Michael and self-deceiving, unrealistic legitimacy, let alone in five years]
  • underestimating Anthony
  • overestimating Vincent

Perhaps Michael could [should?] have handled differently
  • [also Vito] giving Fredo at least a face saving role in the family to show that Fredo is valued in his own right
  • Michael not comforting his wife, Kay who just had a 'miscarriage'
  • Perhaps if Michael had the same “losing the family” talk with Kay......second chance at their marriage
  • The treatment of Tom the only person Michael could trust even though Tom was not the most competent! consigliere
  • Hanging Frankie Pentangeli out to dry
  • Not taking care of the 'dead' capo Frankie's family
  • Killing his own blood brother Fredo
  • handed Mary on a platter to Mosca Another woman dying in place of Michael
