The point was that after Ozma told her about the relics and GoL, she said "Why try to redeem these Humans", meaning she doesn't care for magic-less Humans at all. Qrow said as far back as V4 E8 that "Salem wants the Relics, and if she gets them, it's not going to end well." (a la mass extinction.)

Salem's goal is to divide humanity. That's the point of the Fall of Beacon as well as of Haven. Besides getting the relics, she is sowing chaos. That way, when she gets the relics, the gods will find mankind irredeemable and will exterminate them again.
