I don't know if I want to watch the final episode. The tension has been ramped up and the destruction is underway to kill "a god" we know as Samaritian. Machine's main purpose will prevent it from making a suicide, hence she needed to guide Harold down a singular road. But, yet, I believe her higher calling: "to serve and protect mankind," has given her ability to survive.
It is her need, so a slate wiped clean is a foolish thing. I believe Samaritian fooled himself if he didn't made a contingency plan, and that's what The Machine has done from the very beginning of this series. It created the alias, and made manual backups. It also activated and coordinated other groups, like we saw in previous episode.
Samaritan, in the other hand, seemingly believed in his superiority. After all, it believed to be a god, even though force majure isn't in his hands. Only the choices it made in regards of the numbers. Greer was the same. He believed to be superior in all terms, even though events in the recent past should have pointed him that he was going down a wrong path.
But that is what we humans do. Yet, we learn from our mistakes, even if we sometime repeat them. We learn to forgive and take down those lessons, while we choose with own free will of how things go down at the end. Same way Reese and Shaw chose to go down with Finch, even though he gave an explicit order to go.
What do you think, should we watch the final one, or leave it at this point, where our memories are still golden? Or should we watch it and know that was it?
