Under the Prussian model of education, the primary purpose is to remove free will and turn people into mindless soldiers. Training men to be armed and violent from primary school to high school. The marching, dehumanization via uniforms and shaved heads, bells, id numbers ''color wars'', flags, ''scout staff'' used as a fake gun, and general animalistic behavior for 14 years. I am not surprised in the slightest that he stabbed someone.
