That is not at all what I said, what do you think Kaladin does after Odium is beaten? Continue to follow Dalinar like a dog whose master no longer has need of him? Drift through the skies aimlessly wanting to help a group of people who no longer exists? Do you think Syl will be content with him living standard life? Or governing what land he has?(cause I don't) The watcher is no longer needed when they're is no danger. Brandon has said that there are ways a Radiant can retire, but Syl dieing is a much better option for causing an emotional reaction.
