Derek technically defeated every single 'Big Bad' maybe except for Gerard...He Killed Peter, Killed Jackson (which then saved him), his bite is what activated the mountain ash, he tricked Jenn into healing Deuc which weakened Jenn enough for her to be defeated (eventually). Basically Scott needs Derek way more than he knows.
