What is the poem The Highwayman about?

The theme of something means the universal message that we all get from the excerpt. Not only one single group or classification of people, all the world should be able to get the same message(s) out of a certain piece of literature. The subjects are love, anger, revenge, death, the list goes on and on, but the theme of the narrative poem "The Highwayman" by Alfted Noyes is... You can do crazy things for love.

Another theme is: Love is an eternal bond.

And the second most important message is: One must not kick someone behind his/her back just in order to receive forced love.
