I disagree with everyone who says that they should be killed right now.
Currently, MC is doing a great job of influencing the psychological aspect of the victims, which will cause them to constantly have fear. This will not only kill them physically when MC finally decides to finish it, it will also influence them mentally as they constantly run.
In the end, there are still a few things that MC could've done better. He didn't have to look like public enemy #1 by killing everyone, he should've faked crying, or just attempt to show the injustices.
After this, he should've told everyone that if they protect them, not only will the be killed but their families as well, and the only way to get out of the situation is to take them down.
There's nothing better than their own allies turning against them to survive.
