Really? The Old Testament is full of it; either God smiting various people, or destroying whole cities, or the Jews slaughtering their enemies at God's command:
Make ready to slaughter the infidel’s sons for the guilt of their fathers; Lest they rise and possess the earth, and fill the breadth of the world with tyrants.
Then I heard God say to the other men, "Follow him through the city and kill everyone whose forehead is not marked. Show no mercy; have no pity! Kill them all – old and young, girls and women and little children."
Now therefore kill every male among the little ones, and kill every woman that hath known man by lying with him. But all the women children, that have not known a man by lying with him, keep alive for yourselves.
If your own full brother, or your son or daughter, or your beloved wife, or you intimate friend, entices you secretly to serve other gods, whom you and your fathers have not known, gods of any other nations, near at hand or far away, from one end of the earth to the other: do not yield to him or listen to him, nor look with pity upon him, to spare or shield him, but kill him. Your hand shall be the first raised to slay him; the rest of the people shall join in with you.
This is what the Lord Almighty says ... 'Now go and strike Amalek and devote to destruction all that they have. Do not spare them, but kill both man and woman, child and infant, ox and sheep, camel and donkey.'
Then he went up from there to Bethel; and as he was going up the road, some youths came from the city and mocked him, and said to him, “Go up, you baldhead! Go up, you baldhead!” So he turned around and looked at them, and pronounced a curse on them in the name of the LORD. And two female bears came out of the woods and mauled forty-two of the youths.
