[Roll your dice, if the number is 8 or above (including 8), then Isaac will give up on suicide.]
Eight points...
Ann muttered to himself.
This should indicate that Isaac's desire for suicide... up to now, is still not that strong, isn't it?
Having experienced Ingrid's complete story, Ann has probably also discovered a rule about dice by now.
That is, the criteria for these "events" are not entirely random.
Or rather... this fate determination is like D&D, where there is a Difficulty Class (DC).
The easier it is for them to achieve this event—like "giving birth," like "giving up on suicide"—the lower the required dice value to achieve the event. That is to say, calculated with a D20, the greater the possibility of realization.
Just like Isaac, he actually only has a "7/20" probability of choosing suicide to end his torment throughout this long suffering.
This probability is actually not high.
