The cycles of mistrust, savagery, revenge and violation in the Balkans remind us what a powerful, important force hatred is in the world.
Hatred drives much of what happens, public as well as private.
The Polish poet Wislawa Szymborska comments on hatred in her poem of that title. How easily it vaults the tallest obstacles. How rapidly it pounces, tracks us down. It's not like other feelings. At once both older and younger.
