Antigone. What does this quote mean and what is it's significance?

"Eteocles, who died as a man should die, fighting for his country, is to
be buried with full military honors, with all the ceremony that is usual
when the greatest heroes die; but his brother Polyneices, who broke
his exile to come back with fire and sword against his native city and
the shrines of his fathers’ gods, whose one idea was to spill the blood
of his blood and sell his own people into slavery–– Polyneices, I say,
is to have no burial: no man is to touch him or say the least prayer for
him; he shall lie on the plain, unburied; and the birds and the
scavenging dogs can do with him whatever they like."
