In GF1 Vito sends Luca, his most powerful and most loyal executioner on a fool's errand that results in Luca's demise. In GF2 Michael sends Rocco on an assignment that is even more obviously a ticket to the afterlife.

Now both men were supposed to follow orders. At the same time following orders should not be suicidal. Maybe Luca was too stupid to realize that his attempt at playing double agent would be seen as ludicrous but I would have thought Rocco would have said something like "Uh Mike,not questioning your judgment or anything but after I do Roth, how do I escape again ?" rolleyes

Why didn't Luca or Rocco alert their bosses to flaws in the plan or come up with variations that didn't result in their death?

"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
