Part 12/17:
The speaker discusses how parts like the "angry you" illustrate that some aspects of ourselves are impulsive and short-sighted, focused solely on winning arguments or satisfying immediate needs. When these parts act out excessively—such as in warfare or traumatic events—they risk revealing elements of ourselves so foreign and disturbing that they cause trauma and shame.
In particular, individuals who have committed actions they wouldn't recognize as "themselves" may develop Post-Traumatic Stress Disorder (PTSD). This disorder might be rooted not only in witnessing trauma but also in the realization of actions taken under the influence of impulsive, unconscious parts.
