[Dune] if water is deadly to sandworms why do they attack and eat beings that are mostly water? Does eating a person kill the worm?

Sandworms are not intelligent; they are bestial and operate on instinct.

As territorial animals they will attack and destroy creatures disturbing their domain; their primary method of attack is via their maw.

There are mitigating factors that reduce the impact of lifewater on the makers.

First is size: "adult" sandworms are hundreds of meters long (Paul's first worm ride was a worm that was 2,778 meters long). Their would likewise be a hundred or more meters in diamter.

So imagine our six quarts of blood as less than a droplet.

As well, sandworms generate a ton of heat, so you're probably going to get a little fried before getting swallowed.
