This is a system that puts people in fear. It manipulates and controls to its own advantage—not to the good of the governed, but its own. It has an attitude that hates people and likes destruction. It is adversarial.
Now contrast that with sheep, and especially with a lamb. They must be the most docile of all animals. Biblically, a lamb symbolizes gentleness, innocence, sometimes a childlike vulnerability. It is not aggressive. It is easily led and controlled by a shepherd.
Christ symbolically is the Lamb of God (John 1:29, 36). "Lamb" is used in reference to Jesus Christ twenty-seven times in the book of Revelation. The Beast is an adversary of Christ, and exudes not gentleness, not goodness, not kindness, not innocence, but all of the opposites of those traits.
