Hostor, don't be ridiculous. I believe the only right option is to execute the Blood Mage because he is dangerous to everyone. Why do I think so?
First, he strangles his victims, using wire, or some other similar object. This explains why no one has heard the victims' screams so far. Furthermore, he can also cut their throats, leaving a very deep wound, while the victim makes no sounds other than hissing. Next, and even more importantly: after the murder, he opens the abdominal cavity and cuts out the organs, and then he uses them in his dark Blood Magic for resurrection.
Considering all the arguments I have presented, I believe that the execution of the Blood Mage is necessary for everyone!!! Think about it, people, listen to what I'm saying!!!
Небо – угроз не слышит
Небо – ведёт особый счёт
