Sorry for my English today. What I mean is: How would they have killed Luca, if Vito hadn't sent him to Bruno?


Right.
Luca was Vito's Psycho for Hire and his Dragon. In a lot of books/movies and occasionally IRL, the most dangerous retainer is removed before the attempt on the big boss. If Luca hadn't come calling, Sollozzo would have had people take down Luca at his home. In the book, Luca realizes from a comment Bruno makes that the Tattaglias and Sollozzo have been watching him and verifying his schedule.

"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.
