Greetings in the precious Name of our Lord and Saviour, Jesus Christ.
Yes, there are terrible atrocities and acts of cruelty recorded in the Bible. The Bible records much that it does not recommend. The betrayal of Jesus by Judas is not recommended, it is recorded.
Murders, rapes and cruelty to animals are recorded, but obviously, they are not recommended. In fact, the Scriptures clearly show that God condemns all cruelty to His Creation and will judge those responsible.
