“According to the gamara in sanhedrin, In a scenario that the unborn endangers the mothers life, a goy wouldn’t be allowed to kill the baby and yid would be allowed”
Wrong. That gemara says that there is nothing permitted to a Jew that is prohibited to a non-Jew. Only the Catholic Church says that the mother can’t abort the fetus; Judaism and Protestant Christians say it is okay.
You need to go back to the Beit Midrash.
