I’ve heard it called the ‘bread of shame’ One who depends on others for a livelihood is always going to have some internal rage and be desperately looking for a way to prove his worth. Something similar happens to teenagers stuck in home and school when those their age in past generations were builders and explorers.
Surely our system is not designed so they can orient their skills against the Us instead of in favor of it (sarcasm).
That "shame" comes from a life without love and faith. No family, no church, no one to love them unconditionally, like MOMMY does...and as God does.
Love is complete when we can return that love. It's the old "do unto others..."
MOST teenagers don't turn into ISIS/ISIL murderers. The ISIS/ISIL men (all young) live a life without God, which, as Lucifer will tell you, is HELL = the absence of God.
