PTSD and guilt commonly co-occur. People who have experienced traumatic events may experience something called trauma-related guilt. It refers to the unpleasant feeling of regret stemming from the belief that you could or should have done something different at the time a traumatic event occurred. For example, an abused person may regret and feel responsible of the 'offense' that is taken. A rape survivor may feel guilty about not fighting back at the time of the assault.
