The Spiralling
Bonus Feature: Writer's Commentary Part 4
Demoness: The Demoness was a part of Mindy that was cut off and formed into a different entity born from her years of anguish. Though Demoness was Mindy, there were many differences when she was taken over by this alternate personality, so as such, she deserves a section of her own.
The purpose of Demoness' existence was to wreck vengeance, at any cost, on everyone who caused Mindy to suffer- which is to say, anyone and everyone who was directly or indirectly involved in her parents' demise. She did this at any cost, which meant anyone who stood in her way, whether they were on the side of the law and good or corruption and the bad would be swept aside, decapitated. As rendering vengeance was her only goal, the only thing she cared about, she would have no problem doing this, even if it means killing Dave the way an innocent girl would put the star of Bethlehem atop a Christmas Tree.
Demoness could do this easily and efficiently as she lacks any form of remorse save for those reserved for herself and Mindy, and even that was limited and misguided (very much). Moreover, as Demoness enjoys her work, she would even be motivated to kill off her supposed offenders, going so far as to getting a huge kick out of torturing and mutilating them that she would always try for perfection- Inflicting as much pain and despair as possible for the longest amount of time possible.
As the story marches on in its dark beats, the Demoness was shown to be harming herself and Mindy as well- This is not just to show her dark, masochistic side. The story behind this is that it was also a manifestation of her self-blame. Mindy blames herself for what had befallen her parents and in the story, Marcus. She will keep blaming herself, what with new 'victims' constantly being added onto the list.
The skeleton of her self-blame and subsequent self-hurt consists of both the logical and insensible. Mindy blames herself for her father's death, thinking that could she had been faster, more intelligent and proficient in her skills, she could have saved him. She would go on to think that she wasn't good enough to avenge him, as she actually needed a goofball like Dave or Kick-Ass to save her life twice.
The above could also be a seed to another grief- She couldn't take Frank D'Amico's life by her own hands. That besides the point, as insensible as it was, Mindy blames herself for her mother's death, that somehow she was a deadweight in her mom's womb, causing her to cope poorly to her plight.
That said, Demoness was an elaborate and grand manifestation of all of Mindy's past traumas and insecurities, large and small. This manifestation took the form of a personality as a way to cope, having been bottled up inside for too long, and she suffered immensely for too long throughout the years.
The City/New York/Everyone Else: The Big Apple is also a character on its own, personified by the denizens of the iconic city. In the original movie and comics, the city was portrayed to be slack as the police force was not doing anything to stamp out the city's rash of crime. Another interpretation was that the police was incapable- which is actually a fair argument, with signs of corruption in the form of Detective Gigante.
As a city personified, New York would be feeling hopeless about the crime disease it has suffered; depressed, forlorn, like a stereotypical terminal illness patient.
In the unofficial sequel, New York had a brief uplifting of hope but it was crushed as the disease fought back with renewed vigour. She could still be said to be soldiering on though, as the police had woken up and was planning a death strike on the D'Amico empire all along though of course, the effort was devastated by Demoness.
The city did pull through again in the end, and a valiant fight was put up indeed. Dave's friends were acting like the city's voice when they told him about how the media originating from the city was predicting Demoness' motivations and goals and do not forget; Dave, Aldan and Michael are part of the city...
