When Keeton imagines being a scrambler one of the points that he imagines is that as a sentient being vs non-sentient there’s no mutual understanding to work from as they’re fundamentally different states of being that cannot understand each other. That doesn’t mean the vampires, the human offshoot that does operate in this manner would be more inclined to do so

This passage in particular

Imagine you’re a scrambler.

Imagine you have intellect but no insight, agendas but no awareness. Your circuitry hums with strategies for survival and persistence, flexible, intelligent, even technological—but no other circuitry monitors it. You can think of anything, yet are conscious of nothing.

You can’t imagine such a being, can you? The term being doesn’t even seem to apply, in some fundamental way you can’t quite put your finger on.

Try.

Imagine that you encounter a signal. It is structured, and dense with information. It meets all the criteria of an intelligent transmission. Evolution and experience offer a variety of paths to follow, branch-points in the flowcharts that handle such input. Sometimes these signals come from conspecifics who have useful information to share, whose lives you’ll defend according to the rules of kin selection. Sometimes they come from competitors or predators or other inimical entities that must be avoided or destroyed; in those cases, the information may prove of significant tactical value. Some signals may even arise from entities which, while not kin, can still serve as allies or symbionts in mutually beneficial pursuits. You can derive appropriate responses for any of these eventualities, and many others.

You decode the signals, and stumble:

I had a great time. I really enjoyed him. Even if he cost twice as much as any other hooker in the dome—

To fully appreciate Kesey’s Quartet—

They hate us for our freedom—

Pay attention, now—

Understand.

There are no meaningful translations for these terms. They are needlessly recursive. They contain no usable intelligence, yet they are structured intelligently; there is no chance they could have arisen by chance.

The only explanation is that something has coded nonsense in a way that poses as a useful message; only after wasting time and effort does the deception becomes apparent. The signal functions to consume the resources of a recipient for zero payoff and reduced fitness. The signal is a virus.

Viruses do not arise from kin, symbionts, or other allies.

The signal is an attack.

And it’s coming from right about there.
