Enemy agent, convinced to join up again?

[Mystic]

I experienced the "enemy agent" event yesterday, where one of my own colonists turned betrayer and tried to escape.  I caught him and imprisoned him ... and then automatically started trying to convince him to come back on board.  But after thinking about it, that seemed like it could be a bad idea, so I ended up selling him to a slave trader (and taking the colony-wide morale hit thereof).

So, my question is ... storytelling aside, was there any gameplay reason to not take the risk of winning him back to my side again?  Is there any persistent aspect to the pawn chosen to be an enemy agent that makes him more risky to integrate back into my colony than a typical pawn?  Or is it that once that event ends, he goes right back to being just another pawn, without any further latent, nefarious intentions?

Even robots can become Agents.

The event is random and that is all.
