I have to agree that your intentions were honorable and very pure hearted.
You have done what you could with warning the camp.
I know that some criminals/convicts put on the show of 'getting religion' to get out of prison or for show. And only this young man and God know if he is reformed and has accepted God into his heart or if his intentions are NOT honorable.
not trying to turn this into a religion discussion
But since he had a bad childhood it is possible he was molested also, and repeated the cycle. And also it is possible that he is reformed.
(course I could also watch waaay to many Law and Order SVU episodes !!)
I wish you luck!!! And this young man luck too, he is going to need it.
