We must know evil characters too, in order to counter them.
He could be a good character but he chose another path in his life.
# He was a Joker, but The Fate decided another way
In the Lewis Carrol's books you will never find him. He appears in our books as we need somebody who will represent the Bad

# Maybe you saw such bad characters in your life.
The Joker comes, he cries and weeps
He whispers nasty things;
And though I cannot see him creep,
I know what he thinks.
So many gentle Friends we have
Who’ll make him roll and spin
Thus we secure, thus we save,
The Kingdom we live in..
