Criticism #5: Murder most casual

Through the House trilogy, Count Fenring, who is basically a serial killer, goes around casually murdering people and no one ever seems to notice. For example, at one point he stabs one of the Emperor's concubines to death for pretty much no reason and no one ever mentions it again.

The most absurd example of this is when Piter de Vries, the Harknonnen mentat, kills the Emperor's wife and yet House Harkonnen is not punished, censored or molested in any way. In fact, nobody really seems to care. The Emperor's freaking wife gets murdered and it's not really a big deal. What the hell?

Criticism #4: Bellonda goes bye bye!

I for one was looking forward to Bellonda's role in Hunters of Dune as Murbella's foil. Alas, BH&KJA dropped a bridge on her.

In Hunters, Bellonda gets exiled to monitor spice operations, where she doesn't participate in the plot at all. Her partner, Doria, an Honored Matre kills her in a petty fight. Murbella forces them to share and then both Doria and Bellonda-within get eaten by a sandworm. Nobody ever seems to notice or comment on this.
