Let me arrange this;

Cinder should be Conquest since she got and wanted those maiden powers and made an entire army for herself to take over Beacon. She always get what she wants.

Tyrian is the best candidate for War since he's a psychopath and would love to hurt an innocent fly and the horseman is a psychopath bent in everything that includes carnage.

Watts and Hazel? It's correct here but I'll rearrange if I can learn their personalities even clearer.
