Only 14 and already learning a trade....
My brother in law spent his entire adult life working with violent juvenile offenders, mostly gang members and all charged with serious felonies like violent robberies, rape and murder. He said he would look into their eyes and see nothing. Most would kill him just as easily as shake his hand. He didn’t believe in rehabilitation and said that most were already lost by the time they got to him.
When he retired he withdrew from human contact and spends most of his time gardening or fishing. He has zero faith in the humanity of others. I guess that’s what happens when you spend a career dealing with the worst society has to offer.
