The enzyme’s function is to break down neurotransmitters like serotonin, norepinephrine, and dopamine. Over production of testosterone might be a factor that creates mass shooters. Normal testosterone levels are between 20%-200% of the average, and people whose testosterone levels exceed 400%, are more prone to violent behavior and over aggression. This could be one reason as to why mass murderers do what they do but this alone is more likely than not one of the forefront reasons that they do
