This. The point of the game is the MC is an extremely disturbed individual who refuses to abandoned his urges (violent, sexual, whatever). The idea with his Raptus is there's the voice inside his head almost constantly urging him to become even more extreme. If he listens to the voice, he inevitably self-destructs (gets killed or whatever, depending on the situation). He cannot (or will not) change is base desires and so still will do despicable things. But if he has no self-control whatsoever, he will bring about his own downfall.
