The unlovables

Some are unlovable;
What do we do with them?
If we show them love,
They remain generators
Of hate;
You are kind to them,
It does not stop
Their evil ways;
Smile to them,
They are hard to smile back;
Unlovable indeed, they are;
Yet, we cannot despair;
Love we must continue
To show them;
And keep on in hope;
That one day the gates
Of hatred will shatter;
And love will flow in.
