Should 13 and 14 y.o. killers be sentenced to life without parole

Their lives are pretty much over so yes, they should be locked up for life as sad as it is. Making a dumb mistake at one thing, killing another human being is going down a road one can never come back from. Unless it was revenge killing for somebody executing his loved ones or unless it was a defensive maneuver, I simply can't see him productive citizen without the looming threat that he could kill yet again.
