Sometimes a wish gets lethal
There was this guy who kidnapped his neighbours little daughter, raped her, tortured her, killed her and finally drove her 100 miles away to burn her in a wood. This case shocked the country and it was the first time i heard the wish "This time I hope they do not only find him - this time i wish he will also be burned, so that he will feel what he has done!" more than one time: I heard this special wish for about 4 weeks in which they looked for the murderer from so many people, spread and multiplied by tv and radio, and i thought "can this wish be so strong?".
It was, i am sure. The murderer finally got heavily burned in an fire accident in his basement. He is in coma now, will never look normal again, if he ever wakes up (what i really would appreciate) and they finally found the evidence for his crime as they searched for the reason of the accident. The child remains dead, but i hear the next wish floating and spreading around: "We hope, that such a thing will happen before the crime, next time."
