"PTSD is when something triggers a person to go back almost like an ilusion to the moment they fear so much theyre subconsious hides it away"

Yes, but PTSD causes people to feel constantly alert after the traumatic event took place. It also causes outbursts of anger and/or irritability. People with PTSD can also get startled easily. They can be constantly on the look out for any danger. Finn was startled easy when the Grounders started running (due to his PTSD). He panicked and shot. If you ask me, the massacre was also (in a way) an "outburst of anger" (another symptom of PTSD). Everything I listed above applies to Finn.

The "flashback symptom" you listed is just one of many symptoms of PTSD. It's not the only one. Aside from the symptoms I listed and the symptom you listed, there are also emotional numbing and avoidance. People with PTSD will avoid places, people, and/or anything that reminds them of the traumatic event. They may have trouble expressing feelings for someone or something. They may also isolate themselves from other people.

Finn had PTSD. It caused him to become mentally unstable. In the end, it was the PTSD that led to the massacre.
