The Stalker is Tenno, but he is not defected. He was around in the time of the Orokin, and when Tenno started killing leaders, he did not agree with that, and so that's why he "stalks" you sometimes, and when he sees that you assassinated a leader, he grows vengeful, leaves you a note, and later avenges who you assassinated, attempting to kill you (and, usually succeeds). That is why he made extremely cruel weapons and called them Dread, Despair, and Hate, as in some stages of grief. He just doesn't like the actions of the other Tenno, and so that is why he kills them the most brutal way possible.
