Is a paperclipper better than nothing?

Thought experiment:

Through whatever accident of history underlies these philosophical dilemmas, you are faced with a choice between two, and only two, mutually exclusive options:

* Choose A, and all life and sapience in the solar system (and presumably the universe), save for a sapient paperclipping AI, dies.

* Choose B, and all life and sapience in the solar system, including the paperclipping AI, dies.

Phrased another way: does the existence of any intelligence at all, even a paperclipper, have even the smallest amount of utility above no intelligence at all?

If anyone responds positively, subsequent questions would be which would be preferred, a paperclipper or a single bacteria; a paperclipper or a self-sustaining population of trilobites and their supporting ecology; a paperclipper or a self-sustaining population of australopithecines; and so forth, until the equivalent value is determined.
