I don't think Zervis is sunk yet. Let me explain.

Think about what he said immediately after he did it. To paraphrase: "I'm sick of being around people, so I'm going back to my empire where there are a bunch of people. I shouldn't have fallen in love. No, wait, I couldn't have fallen in love, these tears definitely aren't born of grief, guilt, and self-loathing." His brain was in contradiction mode again, and basically broken at that point.

He killed the person he loved. The one tiny ray of hope he had, the first and probably only chance he had at genuine happiness, gone. Just like that. That'd break anybody's brain and cause them to lash out.

And we still don't know how and why he ended up on Tenroujima, which only Fairy Tail's masters know how to access, much less where it even is. Mavis inviting him there is the only logical explanation, because it sure as heck wasn't Precht or Makarov.
