i always wondered why the Don sent Luca to talk to sollozzo.. i know that vito could trust him because of his loyalty but thats just the thing he is known for his loyalty to the don and that he would rather kill himself than betray him.. vito just had a meeting with sollozzo about becoming partners and than here comes the corleon's best assasin saying he doesnt trust the family... i think vito sent him to his death because he knew that a hit would be taken on his life and luca would have made more problems looking for revenge for his sons if he died and put them in harms way knowing that he is the only one able to stop luca from blowing up the world... what do you think?
