What is hostis humani generis?

The term "hostis humani generis" is a Latin phrase that translates to "enemy of the human race." Historically, it was used to describe individuals who were considered outlaws or pirates, and who were therefore deemed to be enemies of all mankind.

In modern legal usage, the term is often employed to describe individuals or entities that are universally condemned for their crimes or actions, such as terrorists, war criminals, or human traffickers. These are considered to be threats to humanity as a whole, rather than just to specific individuals or groups.

The concept of hostis humani generis has been used in both international and domestic law to justify the prosecution and punishment of individuals who commit heinous crimes that are seen as particularly egregious and harmful to society as a whole. It reflects the idea that certain acts are so universally condemned that they must be punished in order to protect the common good.
