When do UDT and honor yield different results?
"Honor" is not well-defined. He could have meant UDT. He also could have meant something closer to always keeping his promises. Someone using UDT wouldn't keep a stupid promise. They wouldn't make a stupid promise either, but they might not always have been using UDT. They also might not keep a promise to someone insufficiently rational, though that could cause problems with people who aren't sure they're sufficiently rational, people who find out about the broken promise later, etc.
Also, the quote makes it sound like he's choosing honor over the world. The way Eliezer sees it, he's choosing to have the opportunity to save the world.
