cynic v. pessimist v. skeptic

A cynic questions people’s integrity and motives, believing that everyone is driven by selfishness.

A pessimist has a negative outlook not just toward people, but to life in general, and expects or emphasizes the worst in any situation. The opposite of pessimism is optimism.

A skeptic habitually doubts or questions assertions that most people take for granted. Skeptics require evidence before they can accept a claim as true.
