I think your observations are very apt.
It is tragic that no one in that system either saw sufficiently the vision of the kids whole reality
or didn’t have the ability to slice through it with redemptive TRUTH IN LOVE.
Perhaps therefore, God at his point of death gave him another chance. That’s not a Biblical conjecture per se . . . though I don’t know that The Bible ABSOLUTELY prevents it. But I could imagine God giving him a life review in seconds and then another chance at accepting Christ once and for all. We shall see. Certainly there was plenty of reason to say he deliberately and repeatedly CHOSE evil in anger and revenge over his maltreatment . . .
Thankfully, God alone is the judge of all that.
My guess is that many people did try, in many different ways, to help him. And it's not necessarily their fault that they weren't able to turn him around.
I remember watching my older brother pick up a drunk lying in the middle of the street and move him to the sidewalk. As we were walking away, I turned around to look, and the drunk was crawling back out to the middle of the street.
