PLN 14 "Man critical after Colfax Stabbing"

I read "Man Critical after Colfax stabbing" by Monte Whaley, and what matters in this article is the health of both men, the victim and the assasin. The victim was beaten and stabbed once in the chest ob Colfax and Pearl Street. I think that this incident can be related to what Paul experiences in chapter 9 of "All Quiet on the Western Front", when a enemy soldier falls into the crater that Paul is hiding in, Paul abruptly stabs the soldier, to protect his own life. But while the soldier is laying there dying, Paul realizes the magnitude of what he has done, Paul realizes that this soldier is not an enemy, but a comrade. Paul realizes that this man has a mother just like him, and that this man is no different than him. This makes me wonder if the stabbing assasin is mentally healthy at this moment, because he could be going through the same after effects of hand-to-hand killing that Paul went through. While i am not comparing this street confrontation to the horrors of war, death in the heat of battle or death on the streets, death is death. This incident relates to me because i live in the same area that this crime happened, and i am concerned that things like this can strike so close to home. This also relates to the world because crimes like this can occer anywhere in the world, but i think that the effects and the trauma that can happen to the killer, or the victem if they do not die are very similar between all cases of this nature.
