Okay, I know, I'm jumping Head-On into a Hornet's Nest, here, but killing People is always wrong - and erecting Statues for Persons, whose only Achievement in Life was Killing is the Peak of Cynicism.
I'm saying this in a general Sense. There are other Statues, too, that insult my Thinking as Humanist.
On the other Hand, Woody Allen once said: "Comedy is Tragedy plus Time."
Taking this into Consideration, this specific Statue is indeed Funny...
