The great ape body

But then, you can imagine infinite scenarios where this 3d alien race would have a purpose to anihilate anything in its path. It would be difficult for us to understand / agree with these purposes but they are potentially there.

annihilating everything would be a purpose only until the entity would realize annihilating everything was not purposeful ultimately. either with the understanding that everything could not be annihilated because infinity is infinite or due to other reasons.
