I know no one wants the "Cinder is Yang's half-sister by her long-lost mother" reveal, but if it turns out to be the case, it might explain her motivation--might. If Cinder has beef against Hunters she could be trying to show how useless they are by: infiltrating the top school for Hunters (who are supposed to be able to notice things); defeating or neutralizing the best up-and-coming Hunters; damaging or corrupting the CCT to prove that the Hunters cannot protect anyone.

To be honest none of this sounds that great, and I am eager to (finally) find out more of Cinder's plans and motivation. But all in all, not a lot of it makes sense right now.
