In the story, Jace shows compassion towards Clary through his words. In the text he says "I have to turn myself in- and the Cup, too"(76%) This shows that he would rather sacrifice himself, rather than have Clary live a fake life with the other Jace. He also shows despise for the other Jace and doesn't want Clary to stay with the other Jace, even if he risks inprisonment or even death.
