* Kesef Mishneh on [[Sanhedrin 57b]], In the case of murder, if the Noachide slay a child in its mother's womb, or kill a person whose life is despaired of ("ṭerefah"), or if he cause the death of a person by starving him or by putting him before a lion so that he can not escape, or if he slay a man in self-defense, the Noachide is guilty of murder and must pay the death-penalty, although under the same circumstances an Israelite would not be executed
* Leḥem Mishneh & Kesef Mishneh on [[Sanhedrin 74b]], The Noachid is free from punishment if he commits a sin unwittingly; ignorance of the Law, however, does not excuse him. If he commits a sin under duress, even one for which an Israelite is obliged to undergo martyrdom rather than transgress (e.g., idolatry, adultery, or murder), he is not liable to punishment
