In case anyone's thinking of ST III: Kirk only stole the Enterprise
- an EMPTY Enterprise
, not one with a full crew aboard, unlike April's actions - to help Spock. And he was fully prepared to face the consequences of his actions afterward. Kirk did not violate the Prime Directive and intervene in anything like April did at Phaedus.
What April did there is basically the same as Captain Tracey's actions at Omega IV, and April is no better than Tracey, really.
