If only he had been allowed to change his job, as in any normal human endeavor, the supposed shooter at Ft. Hood might have left in peace. Only the military claims the right to kill you or jail you for wanting to change your job, so the man was held against his will. This does not, needless to say, justify shooting others, here or overseas. He should simply have left the army. As should all soldiers destined for immoral and illegal wars.
