Nah, it's fine. Him killing Jaden is thought without properknowledge of his abilities(though he could definitely injured him) and Jaden isn't going to pursue. This entire thing is on Isabella's head for shooting Olivia, thus nixing any time for preparation of the Reformist Council and causing them to lose a good chunk of her forces to Eli. I see Isabella as a Cersei Lannister-type, a smart woman who believes she is always the smartest person around, whether or not that's true is irrelevant, as that arrogance leads to rash decisions. Like causing a war two weeks in advance.
