The Postal Dude presents himself as a calm and easy-going person, but this demeanor is a thin veil for his true nature as a self-proclaimed 'equal opportunity lunatic'. He is prone to extreme violence, which he casually justifies as self-defense. He is also a meth user, a habit that likely contributes to his erratic and unpredictable behavior. Ironically, despite his petition to force congressmen to play violent video games, he personally dislikes them.
