Because there's a whole country to destroy!
You're probably right, there, Lazamataz; "because there's a whole country to destroy."
I am sure psychologists and psychiatrists have mentioned the subject too many times to count--about how there are two sorts of people, those who build and those who tear down.
From reading the pharmaceuticals DUmmies brag about "having to take," one speculates many of them are in the "tear down" category.
