Many people speculate that Cinder can not be dead and she may even come back in the next episode and attack Raven and Yang. Okay, as long as there's the slightest possibility of survival, I do not think there's any chance Cinder has the strength to go back for a while. We will see:
When Cinder and Raven fall to the ground, both are exhausted, but Cinder is in a much worse state, she is on the ground and breathless while Raven stands proud and composed. This shows that Cinder took much more damage during the fight and her body is already reaching the limit.
Soon after, Raven hits a critical blow to Cinder's head that destroys his mask and throws it right into the abyss. Head blows often cause great damage and stun the opponent.
See that it was a really strong blow.
Then Raven freezes Cinder as she falls.
Many claim that this would not be a problem, since Raven herself was frozen and returned and Cinder has firepower, but it seems the situation is very different in this case. When Raven was frozen, she had her aura intact, and the way Cinder used the ice power was different, she did not have flaming maiden eyes and Raven was. This difference might mean that the freeze that Raven used was much stronger, meant to kill Cinder, and Cinder did not want to kill Raven when she froze she, wanted her to be paralyzed when she saw her colleague dying and having her power drained.
If Cinder survived ... she's going to be out of action for a long time.
