A Good Cause

You thought that since she is blind she would not be able to feel it. You bring the pepper spray up to her face and press the trigger. A red mist sprays out of it and into her eyes. She screams in pain. It turns out she can feel it. Her eyes and all around them go red with irritation. She starts to shake violently. It looks like she is having a heart attack. All of the sudden she just stops moving, you are pretty sure she is dead.
