thrill killing

A Thrill killing is a nickname for a kind of premeditated murder committed by a sane criminal who is motivated by the sheer excitement of the act. Soldiers have recorded that the murder of helpless prisoners, men, women and children gave them a thrill, even in brutal cases such as bayoneting the wounded.
