Why Poem by Tango

Why? Cant mankind live together in peace.
Why? Does he have to maim, and kill like an untamed beast.
Why? Is he never contented with his lot.
Why? Does he always desire what someone else has got.
Why? Can't he pray to his own particular lord.
Why? Can't he make ploughshares out of his sword.
Why? Can't he raise his children, in the way he desires.
Why? Must he live in fear, that they will be killed my some madman's fire.
Why? If there is a god, as everyone is led to believe.
Why? Doesn't he stop all this senseless killing, and disease?
