Can any jews explain this to me ??

[improover]

With regard to bloodshed, if a gentile murders another gentile, or a gentile murders a Jew, he is liable. If a Jew murders a gentile, he is exempt. Evidently, the term liable is used in the baraita.
sanhedrin 57a

the punishment of a gentile who studies Torah is like that of one who engages in intercourse with a betrothed young woman, which is execution by stoning
sanhedrin 59a
