malevolent

The main character of “The First Shadow” is Henry Creel, an adolescent dweeb who looks like Pee-wee Herman but has a malevolent side that could give Carrie a run for her prom night money.

But in Nozick's version, there were no malevolent AIs; it would be "provided by friendly and trustworthy beings from another galaxy".

He has the preternatural ability to contort his facial expressions ever so slightly, going from innocent to cold and malevolent and back again in a split second.

In that great play, part of the pleasure is teasing out when the host couple, George and Martha, are playing a malevolent prank on their guests or tearing each other apart for real.

And it’s an attempt by the truly malevolent to weaponize their dangerous ignorance, to make their viciousness normal—and to implicate all of us in their inhumanity.
