Can you discern any pattern or purpose to the violence in the world today?

But that day belongs to the Lord, the Lord Almighty—
    a day of vengeance, for vengeance on his foes.
The sword will devour till it is satisfied,
    till it has quenched its thirst with blood.
For the Lord, the Lord Almighty, will offer sacrifice
    in the land of the north by the River Euphrates.

~Jeremiah 46:10
