Well cortana doesn't have much of a backstory and could actually be based on a dead person. The only illegal thing is that she's "expired." And also, surgery for a fragment can give you an inverted dick according to York XD. But seriously, I don't know if what I'm going to say is right but I think that John was probably going rouge in halo 5 just like the meta when he had all the fragments. From what I think, the fragments were probably equall to a whole AI and since he only had surgery for sigma. Also like cortana, sigma had a crave for power which affected both John and meta in a similar way. The reason John is still alive is because he was able (I think) to let go of cortana rather than the meta dying with the fragments. My last question though is if meta had almost all the fragments, how come Charon could recover them?
