@RustyCrab@Inginsub Really? It's been a while since I read it. The Harkonne only appear at the beginning, successfully doing a raid on Arrakis through careful scheming and at the end when they get overthrown.
The book is primarily about Paul getting to know the fremen and learning their ways.
Harkonen is definietly meant to be a stark contrast to atreidis. They scheme, are tyrannical, glutenous, psychopatic, sexually deviant.
I guess in a way Dune is also about good people winning against bad
