Violence can be contagious. It's in the Bible, Proverbs 16:29, NIV. "A violent man entices his neighbor and leads him down a path that is not good."

The unfaithful have an appetite for violence. It's in the Bible, Proverbs 13:2, NIV. "From the fruit of his lips a man enjoys good things, but the unfaithful have a craving for violence."

Don't imitate a violent man. It's in the Bible, Proverbs 3:31, NIV. "Do not envy a violent man or choose any of his ways."

Those who are violent will suffer violence. It's in the Bible, Matthew 26:52, NIV. " 'Put your sword back in its place,' Jesus said to him, 'for all who draw the sword will die by the sword.'"
