Jason really gets me hear. I love him. I agree with icon that what he's asking isn't right, but it's right in terms of where Jason's coming from. Because it's really not, as I read it, about Jason's philosophy or Batman's. It's that childish need for Batman to love him before anything else. It's like in fairy tales the way there's something comforting about the witch in Rapunzel who wants to lock her away from the world--she's wanted.
Jason woke up in a box and felt like the whole world had just forgotten about him. Of course he'd fasten on some symbol that proves Bruce cared about him more than his mission. He made it an impossible symbol, of course, and underneath I don't think he really wants Bruce to betray his own principles. He just wants to feel like he mattered. Or more likely, he's proving to *himself* that Bruce never really loved him. Which he's doing here--how much clearer could it get? Shoot me, or shoot him. It's a twist on the "who do you save" situation.
