That’s the joke, because you’re cherry picking just from the new testament.

Probably one of my favorite bible passages is the one where God sends a couple female bears to murder 42 kids for calling Elisha bald. 2 Kings 2:23-24

Here’s another pretty good one, where God commands Saul to slaughter literally everyone (including children and animals),"3Now 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. " "9 But Saul and the people spared Agag, and the best of the sheep, and of the oxen, and of the fatlings, and the lambs, and all that was good, and would not utterly destroy them: but every thing that was vile and refuse, that they destroyed utterly. "

So God said he wasn’t king anymore because he didn’t slay absolutely everything and everyone in the city.

“11It repenteth me that I have set up Saul to be king: for he is turned back from following me, and hath not performed my commandments. And it grieved Samuel; and he cried unto the LORD all night.”

Any rational human being should be able to see that murdering “infant and suckling” is abhorrent
