If she wants to stop Regina from being born (which like Snow says, would probably happen if Eva is killed), then Regina's heart wouldn't exist to be an ingredient in her spell either. Or more generally, if Zelena changes the past so that she gets everything that she ever wanted then why would she have the motivation to cast the time-travel spell in the first place?
