If Tessio had succeeded in whacking Michael, how would it be guaranteed that he would be the next Don? And who was Barzini anyway to tell him that he could have control? What would ultimately happen to Clemenza as well? Do you think Tessio would have assasinated Clemenza, Neri and Rocco to take control? Furthermore, Tessio would have probably ended up playing himself...Barzini ultimately would have hit him. Why, BECAUSE NO ONE RESPECTS A TRAITOR. Any thoughts to the above questions?? Holla Back...
