On how to treat Gentiles has such great advice as
If a Jew is chasing a gentile in order to murder him, it is forbidden to kill the Jew in order to save the gentile, even if there is no other way to save the gentile’s life. A person who kills the Jewish pursuer in order to save the gentile’s life must be put to death. But if a gentile (or a Jew) is chasing a Jew in order to murder him, one must kill the pursuer in order to save the pursued person (if there is no other way to save his life). This law applies to a ger toshav as well.
