Beatrice died because she lost interest and gave up in her own game. At least I know why she just died then.
Witches setting up games like this is suicidal then because there's always a chance they'd die from boredom. Beatrice had her reason of 'showing Battler something' to do this, but this is some fancy way to kill yourself. Maybe witches aren't able to commit suicide conventionally which is why they had to go this far...
