The chivalric order is nothing but a laughing stock anymore. Basically the army robbed their achievement and instead pushed blame on them. Looking at Cody, he left that sinking ship a long time ago, and became a drunkard, but is Vincent still there? Or does the chivalric order even exist anymore? It might be a mere ceremonial force at this point. Quite interesting developments, and in fact this is far worse than happened in the game! You'd think the chivalric order had plenty of supporters and sponsors among the nobility since even the uber conservative Stokes family considered joining it a great honour, but now it looks like Justus had managed to remove all of its backers, without anyone noticing. Who knows how he bought all of the relevant nobles.
Yes, it's ironically funny that by trying to make things better, Harold might have actually made them worse. He even offered that chance to Justus on a silver platter by presenting himself as a deserter and a spy. You'd think he would now low-key sabotage whatever projects Justus reveals to him, but I don't think he has the guts for it. I hope he's at least leaking everything he learns to the Sumeragi. But then again, it's also possible Justus doesn't really give him any important jobs, just menial tasks that require strength but include no particular secrets. Like collecting samples, dealing with experiments running amok, and that sort of things.
