In Funny Business, Jeannette crossed this trope in a flashback after realizing that she had abused her Reality Warper powers as a toddler, to cause real harm to people and has remained in this state for more than seven years.
In Worm, Taylor crosses it after failing to prevent The End of the World as We Know It and witnessing the devastation caused by Scion's rampage, which killed her father. She would have killed herself if not for Tattletale.
