Murder, huh? You do not even understand the situation. And yet you are playing the judge, huh? The Bible says that anyone wo hate his brother, is a manslayer (1 John 3:15). And, since we are all related through Adam and Eve, we are, in a sense, brothers and sisters. Those people who do not want Jesus as king, as of the moment that he says to bring them and slaughter them before him, will have tried to murder off all of Christ's family (please see Revelation 11:7-10). When someone tries to kill off a bunch of innocent people, what is that called and what is the penalty for it? What is worst, these are friends and family of Jesus. What would happen in any government if the friends and family of the high up officials were murdered? Something else to keep in mind: if someone were to start a war in order to kill off all of a certain type of people, would simply making a law saying they cannot cause those people trouble anymore work to keep them safe? How many people do you know who, if they got angry to the point of murder, would let up on their murderous ways just because of a law? That is why, on account of the holy ones, those days would be cut short (Matthew 24:21, 22).
