Evil

Behavior that knowingly causes harm or injury (either to a group or to whomever happens to be in the space at the moment); by either individual or institution; often justified by being in service to some [perhaps so-called] higher purpose.
The nature of an individual habitually and deliberately bringing harm to a target individual, over time and with consistency and in a form not obvious to others, for their own amusement, coupled with a willful obliviousness to the damage wrought and persona of high ideals and respectability maintained by incessant lying to self and others.¹
