We judge others more harshly than ourselves or our friends and family, it’s often a tribal artifact of the environment our species grew up and evolved in through its infancy that has in part informed our acceptable behaviors as a social species who relies on groups for survival (justice, altruism, fairness, social contract, etc).

Sometimes it’s hyperbole, sometimes it’s incorrectly treating people different than ourselves as less than instead of different to, and sometimes someone violates common morality so abjectly that capital punishment is a popular acceptable outcome.
