Riddle of Renounciation

That foolish servant, didn't know how good he had it. I ensured his safety, yet he wished me ill. Luckily I left this little catch for such an instance of insolence.

    My, oh my, what a life you lead
    You can fight all you want but not once will you bleed.
    Bound in forever, a slave to Jack's cause
    When he gives an order you act without pause.
    So how will it end, your immortal life?
    Certainly not at the point of a knife.
    Instead it's these words, etched in your being
    Your demise is near, I'm sure you're seeing.
    Say your last words before the following line
    If you do not you'll run out of time.
    That's it; the end. the final attack
    Now turn yourself back to before Red Jack.
