'Desperate' in the Bible

On the seventh day the baby died. But David’s servants were afraid to tell him the baby was dead. They said, “Look, while the baby was alive, we spoke to him, and he wouldn’t listen to us. So how can we tell him the baby is dead? He may do something desperate.”

Hushai continued, “You know your father and his men. They are warriors and are desperate like a wild bear robbed of her cubs. Your father is an experienced soldier who won’t spend the night with the people.
