We have here a story with a minimum of information and yet posters project their own world views on the situation to determine that the "the cost effective route to keeping society safe from these creeps is execution.. tough love."  So we see that with almost no information we are willing to consign an individual to death.  If indeed that man has a long history of actual abuse of children or others, he should have offending organs surgically removed.  Resulting altered hormone levels may allow his effective integration into society.  

We are told that sexual orientation is hard wired.  So it is useless to call offenders creeps.  On the other hand, rewiring the hardware could alter behavior.  More productive.
