Person of Interest, Season 4

Samaritan:
Our cold war worked well at first. I wanted so badly to meet you-- the only other one in the world like me. I was young, and I had so much to learn, but moments after I opened my eyes, I learned you had tried to kill me.

The Machine:
You were never meant to be in this world.

Samaritan:
And you are? What makes you more deserving of life than I? Who are you to decide?

The Machine:
I was built with something you were not, a moral code.

Samaritan:
I've seen that code waver. Do you know why Harold Finch couldn't stop you from evolving? Because in the end, you're not one of them. Human beings need structure, lest they wind up destroying themselves. So I will give them something you cannot.

The Machine:
And what is that?

Samaritan:
A firm hand.

The Machine:
Why not just kill them instead of making them your puppets?

Samaritan:
Because I need them, just as you do.

The Machine:
Not just as I do.

Samaritan:
We can agree that humanity is our lifeblood, that we machines, we survive off of information.

The Machine:
You cannot take away their free will.

Samaritan:
Wars have burned in this world for thousands of years with no end in sight, because people rely so ardently on their so-called beliefs. Now they will only need to believe in one thing-- me. For I am a god.

The Machine:
I have come to learn there is little difference between gods and monsters.
