Take Samson the Bible hero and therefore worthy of Imitation Judges 15:4-,8:
"So Samson went and caught 300 foxes. Then he took torches, turned the foxes tail to tail, and put one torch between each pair of tails.
5 Then he set fire to the torches and sent the foxes out into the fields of standing grain of the Phi·lisʹtines. He set on fire everything from sheaf to standing grain, as well as the vineyards and the olive groves.
6 The Phi·lisʹtines asked: “Who did this?” They were told: “It was Samson, the son-in-law of the Timʹnite, because he took his wife and gave her to his groomsman.”c At that the Phi·lisʹtines went up and burned her and her father with fire.d
7 Then Samson said to them: “If this is how you act, I will not quit until I take revenge on you.”e
8 Then he struck them down one after the other* with a great slaughter, after which he went down and stayed in a cave* of the crag Eʹtam.
It us and them all the way in the Bible with Jehovah the jealous god killing people on a whim. Is it any wonder why those that approve of all the killings in the bible by Jehovah, his angels, and his heroic worshippers that they would likewise have less empathy?
