If utf possessed you, technically it was urf's soul that was cursed after killing the puppies. the curse will imprison his soul in a dark, impenetrable forest where day will never come(eternal night),and it will never stop raining. he will also get his body incinerated.
He will be tortured with vary painful pain and will always be close to death with only a half chicken thigh for hunger and a half heart for health.
His soul will be there long after the bad stuff and the good stuff.
