Libertarians have something good to say on the matter in the non-aggression principle, which simply stated says, “Do not aggress against others.” We should live and let live and not take what is not ours nor compel others by force or they have every right to defend themselves. This is similar to the biblical truths laid out by Jesus, “Love your neighbor as yourself,” or in other words, “Do unto others as you would have done to you,” for “He that loveth another has fulfilled the law.” This includes His teachings on turning the other cheek and being forgiving. If all people were to do this, we wouldn’t have to read an article on how God says it’s okay to defend the innocent from the wicked, even with lethal force. Striving with a man who has done you harm is allowed; striving with a man who has not is not, according to Proverbs 3:30. Some would define this as God’s most basic morality.
