Cane gave Aria a quick and easy death, because in a way she didn't mean to harm the others intentionally. It was a lapse of judgment and how blinded she was by her own desire that caused her own demise.
But, Mason was still alive, as were a few nasty people from the Blue Moon pack, as they constantly begged to be killed, instead to live their lives.
Cane was someone who thought death was too easy of a punishment to be paid for people's crimes, they needed to live and beg for death instead.
Death was only one way and a quick torture before everything ended, but life… Cane could think of a thousand ways to make one dread living with every breath they took.
If there was one thing that he learned from his slavery, it was; death was an escape for people to leave their misery behind.
Therefore, how could he let his enemy escape so easily?
