Jean-Luc Picard: If your issues are with me, then deal with me. This has nothing to do with my ship... nothing to do with the Federation. Shinzon: Oh, but it does. We will no longer bow before anyone as slaves not the Romulans and not your mighty Federation. We are a race bred for war and conquest.
When Picard tells Shinzon to leave the others out of his issues, Shinzon simply expresses a desire for conquest.
