I think it depends on how and why they go rogue. Do they lose faith in the UNSC? do they just want a chance at a normal life? There are all kinds of Reasons. Three of my Spartan-II's have gone Rogue: Two after augmentation, with one committing suicide, and the other one joining the Insurrection. The third, after seeing the corruption that has taken hold of it, leaves the UNSC and creates a rebel group at the age of 93.

Like I said, it all depends on why the SPARTAN-II would do such a thing. Even with their loyalty to the UNSC after their intense training, they still have the ability to choose what to do. There would probably have to be some circumstances to make them completely lose faith in the UNSC.

I hope this helps.
