The ending wasn't very conclusive. Put yourself in snowman's position. What would you have done? why?

Ultimately, this situation, and its outcome, hinge on how Snowman identifies. In the last chapters of the novel, Snowman is seen to have shifted his way of thinking and, to a certain extent, his own understanding of how the world works to that of the Crakers. Such a shift is predictable as the Crakers are the only sentient beings with which he has contact. Extremely limited in their knowledge of life before the release of the virus and unable to read, the Crakers world is very small. Snowman has adjusted to this. The arrival of three humans tests his allegiance, not only to the Crakers, but also to the entirety of the project planned by Crake.

As Snowman approaches, he is filled with questions and doubt. The book ends on a cliffhanger, as Snowman’s ultimate decision is not revealed. This forces the reader to imagine what might happen given their knowledge of Snowman’s past and present experiences. I predict that at this point Snowman might get rid of the humans. I would have gotten rid of the humans to protect the Crakers.
