Hell is for Heroes
There were two instances in the movie that are relevant to self-defense and attacking back.
The first was when Steve McQueen was fighting hand to hand in the trenches as they were being overrun by German soldiers. McQueen grabbed his steel pot (helmet) that had been knocked off and hurled it into the German soldier's face from a couple feet away and then closed with him to finish him off with his knife. We must always be prepared to use anything and everything at our disposal to fight back with.
The second scene that stood out in the movie was after McQueen's heroic death when he blew up the pillbox. They showed a soldier who witnessed the event puking. This stands out because real violence and the serious consequences of violence often elicit such reactions. This is why being aware and avoiding violence is so important, and why you should only attack back as a last resort. If you fail to avoid something because you were not aware, you have no choice but to attack back. With any physical encounter, you risk being seriously injured or killed. Even if you survive, you may face criminal or civil proceedings in the courtroom and will have to live with what you have done. Avoidance really is the best option, but be prepared in case it is unavoidable.
