Why do regulators in The Fifth Personality have to kill philanthropists?

In the game The Fifth Personality, each character has his own background story and special abilities. The supervisor is the killer role in the game, while the philanthropist is the survivor role. The game sets a hostile relationship between the supervisor and the survivors, and the supervisor will hunt down and kill the philanthropist. Philanthropist Kreacher Pearson is a flexible role in the game. He has a flashlight, a special prop, which can be used to light up the environment and make regulators lose their ability to act in a short time. This makes philanthropists have the ability to escape and intervene in the game. The relationship between the setting of the game and the role is to increase the tension and antagonism of the game. The supervisor's goal is to hunt down and destroy survivors, and survivors should escape the supervisor's pursuit by using skills and props reasonably.
