a misanthrope so pure she can't understand why solitary confinement is considered punishment.

The word misanthrope is human to the core—literally. One of its parents is the Greek noun anthrōpos, meaning "human being." Its other parent is the Greek verb misein, meaning "to hate." Misein also gave English misogamy ("a hatred of marriage"), misogyny ("hatred of women"), misology ("a hatred of argument, reasoning, or enlightenment"), and misoneism ("a hatred, fear, or intolerance of innovation or change"). Anthrōpos also joined forces with phil- (a combining form meaning "loving") to form the Greek ancestor of philanthropy ("active effort to help other people"). We also find anthrōpos when we delve into the foundations of the word anthropology.

Misanthrope comes from the Greek misanthrōpos “hating humankind” and was very likely popularized by the French playwright Moliere's Le Misanthrope, which depicts a bitter critic of society who chooses exile over contact with other people. In English, misanthrope (or its anglicized equivalent, misanthropist) has been applied to many a perceived antisocial crank, from satirist Jonathan Swift to philosopher Friedrich Nietzsche to Charles Dicken’s character Ebenezer Scrooge. It is one of several English words beginning with mis- (from Greek misein "to hate") naming persons who despise something or someone. The most familiar example nowadays is misogynist, used of a person who hates women. Two lesser-known variations on the theme are misandrist “one who hates men” and misopedist “a person who hates children.” https://www.merriam-webster.com/dictionary/misanthrope

 Rather she is the genuine article, a misanthrope so pure she can't understand "why solitary confinement is considered punishment." — Lewis Burke Frumkes, New York Times Book Review, 10 May 1992
