• Luca's ridiculous mission with that idiotic story

What if Vito had sent Sonny? instead of Luca, to “find out what they had under their fingernails”

Would Sonny have been more believable less ridiculous less idiotic -- considering Sollozzo saw Sonny was hot for his deal and may not have been suspicious?!

Sonny: “I am here purely on a [further] fact finding mission to try to convince Pop because I [and Tom who "knew it was the right thing to do"] believe narcotics is a thing of the future" or similar cover story! or that's an impossibility -- that could never happen....

• Sonny's self-destruction

Would Tessio seeing Sonny was running everything into the ground and pretty soon, there won't be one place in Brooklyn Tessio can hang his hat! switch sides to Barzini, to speed things up?

Tessio won't have to set Sonny up to be murdered as Tessio did with Michael. Sonny would do it all by himself!

What about Clemenza? There won't be nothing left to build on....

He did ask Freddy if he wants me to get a different bodyguard and he said "no."
