His self-awareness is simple: there is his anger against everything else. He has no sense of correlation, nothing to link cause to effect. He knows only one 'other' – a quiet voice saying 'yes', or 'no, not that one.' He doesn't think about listening or not listening. He is angry either way.
He cannot be contained – locked away, he turns in on himself until there is nothing but the rage: no lock, no confinement, only violence.
He can be tempered, a balance reached: the other saying 'take this injustice, this system, this broken world, and let us rage against it together.'
