You people saying you would let your die are just taking the moral high road for an answer.
If your child was laying in the ICU and facing death, you would do anything you had to in order to save his life. If a pedophile guranteed 100% that his life would be saved, would you really sit there and condemn your child to death?
Especially when there is no rules saying that when your child recovered you couldn't stop yourself from letting him watch you beat the pedophile to death.
