It's not bullying, so much as divine retribution. At least, it doesn't seem like god has given her a full bladder to teach her a lesson.
More like she decided that it wasn't because of God that she made more like she assumed she did it herself and said he didn't exist right after doing so.
As punishment, God decided to ignore her the second go around and will just erase everyone who saw her pee herself memories as mercy once she truly reforms.
