I suspect you are right, I really don't know much about them. I just felt sorry for the ones I saw interviewed. There must be some hope for them, though. Many do come out of that lifestyle, by the grace of God.
I think the ones who get to the bug-chaser stage are essentially beyond redemption. Perhaps I should have more faith, but I think there are some boundaries which, once crossed, cannot be revisited. There are Rubicons in life, as in war.
I admire your sensitivities however!
