I know what you are saying. Trust me I do. I guess, I never give up HOPE, but yeah...........my statement needs qualifiersSpeaking strictly to an earthly viewpoint, I would disagree. I agree that MOST humans are able to reform themselves if they put effort into it. But not all, as your statement would imply.
There are some who, despite all efforts, resist good efforts and end up essentially worthless, and potentially doing evil. Some folks will drink themselves to death, no matter how many times they run the program. Some will forever be slugs and would walk away from a well-paying just because they just can't seem to put the effort into it. Some folks can't muster enough intelligence to survive the streets. The list goes on and on ... I've seen it first hand more times than I'd want to recall. I worked as a detective for a few years in sex crimes; some of those folks are undoubtedly past any hope.
Not to say that this hard line exists for burbguy82's problem; the child he speaks of is probably not "evil", but just lazy. There's a distinct difference.
No human is irretrievable! But they need to forgive themselves first.
