Let's take it through the cycle. Snow has Emma, person has grudge against Emma travels back in time to kill Snow and succeeds. Emma is never born, person has no reason to have grudge, therefore has no reason to travel back in time to kill Snow, so does not. We're stuck in an endless cycle. To avoide this the villain would need to get him/herself in the past to kill the enemy.
