Without spoiling anything this is one of those films that seeks to appeal to a fantasy most healthy people will never have, but by doing so, tries to make you feel like it could be normal to have: you can kill those who mistreat you and society will be willing to help you blame it on someone else. The moral of the story seems to be that if you mismanage your mental illness, despite having every opportunity to do the right thing, you will still be forgiven for blowing your life up. This is beginning to be a trope that has become, sickeningly, all too common in our increasing, blame-shifting and irresponsible society.
