End of the Empire's last ability will trigger at any point it has no fate counters on it and the ability is not already on the stack. If it is countered, it will simply trigger again.

As End of the Empire's ability resolves, you must sacrifice it if able. If you can't, for example you no longer control it as the ability resolves, the rest of the ability does nothing.
