Usually, everything in the Imperium serves a purpose. They'll do whatever is necessary regardless of morality. That's where the meme of "no goodguys" comes from. But in this setting, in order to survive, they MUST do some unsightly things to continue to exist.

Using humans as computers isn't for fun, it's a necessity due to the rules of the setting. Otherwise why strap a person into a machine and jab wires into their brain? That's alot of work.

So... With all that in mind... what are the beastwomen useful for?
Certainly not meat or hides, they're too scrawny. Certainly not milk, there are much better options for that.
If it's because of malice, then fine. But stop wasting precious time, space and resources keeping them alive and just put a bolter through their heads and be done with it.
