Is he really the mastermind behind the game? Wohohowow

When did they mention that there was a mastermind behind the game? He simply kills as well. There are the main respawned killers and then there’s him who kills when someone is in the way of the time he wants to have alone with Bada.

True, if someone says more then hi to bada, doha instantly thinks they are better off dead.

The ending is probably just doha wanting to keep bada in the game.
