You can be a stand-up Marine for your entire career. Make a stupid 5-second decision, it will stain that stellar white career for the rest of your life. How many Marines have been honorably discharged, being diagnosed with PTSD? It's hard to ask for help, but at a certain point, you are responsible for your own actions. I know many Marines who have PTSD. They have learned to recognize certain situations that trigger it (crowds, drinking) and avoid them for theirs and others safety.
100 character witnesses at his ADSEP board will be a waste of time. The recorder will just play the video. But he's probably going straight to dishonorable, anyway.
At the end of the day, he'll be known for his stupid 5-second decision, and not his years of unblemished service. That's on him alone.
