In my "current" novel, I need a reason for my character to continue on with the adventure after a violent encounter with the enemy forces. If my character is an "adventurer" of sorts, does curiosity and determination work as a plot device to propel him onwards after a violent event that would deter most people? Another aspect is that several people he has worked with in the past and considers friends, although not close friends, are killed during the event. Would a desire for vengeance work? What about a desire to carry out vigilante justice and make those responsible, who would otherwise escape, pay for their crimes? Thanks for the input!
