In Christian Theism God is perfectly good and Holy and is the transcendent and eternal law giver and anchor for morality (God by nature is perfectly good). (Disagree or Disagree ?)
Jeremiah 13:14 And I will dash them one against another, even the fathers and the sons together, saith the LORD: I will not pity, nor spare, nor have mercy, but destroy them.
Samuel 15:3 Now go and smite Amalek, and utterly destroy all that they have, and spare them not; but slay both man and woman, infant and suckling, ox and sheep, camel and ass.
Samuel 6:19 And he smote the men of Bethshemesh, because they had looked into the ark of the LORD, even he smote of the people fifty thousand and threescore and ten men: and the people lamented, because the LORD had smitten many of the people with a great slaughter.
Amos 3:6 Shall a trumpet be blown in the city, and the people not be afraid? shall there be evil in a city, and the LORD hath not done it?
Isaiha 45:7 I form the light, and create darkness: I make peace, and create evil: I the LORD do all these things.
Ezekiel 5:10 Therefore the fathers shall eat the sons in the midst of thee, and the sons shall eat their fathers; and I will execute judgments in thee, and the whole remnant of thee will I scatter into all the winds.
Ezekiel 5:16 When I shall send upon them the evil
arrows of famine, which shall be for their destruction, and which I will send to destroy you: and I will increase the famine upon you, and will break your staff of bread:
So will I send upon you famine and evil
beasts, and they shall bereave thee: and pestilence and blood shall pass through thee; and I will bring the sword upon thee. I the LORD have spoken it.
I'm curious as to how you define "good".
