Subtypes - Risk-taking (including histrionic features) @ Wikipedia

"Dauntless, venturesome, intrepid, bold, audacious, daring; reckless, foolhardy, impulsive, heedless; unbalanced by hazard; pursues perilous ventures.

These individuals are easily bored and seek activities that will excite them. These could be brutal assaults, murders, sky diving, pranks, doing dares and putting one's life at risk. The violent activities, such as murder and assault, are not necessarily sadistic in nature but more of a rush or thrill for the perpetrator. These are reckless and bold individuals who have no regard for their own safety or the safety of others."
