When the story is over I'll judge it.Even this is more that anything Seven got so far. And don't forget: The Context is King. In Jadzia's case there were enough other scenes where Jadzia also struggled with the idea of the revenge (especially after the revenge). In Seven's case, we have a main char, that didn't struggle with this until now or had any consequences. And this is not the way, the Trek universe did work in former shows. So, like in the case of some similiar acts by Archer, I just want to see something more than a Seven, that now has to be "immoral", just to let Picard shine a bit more.
I'm not worried about it in this context.
And then he has his log entry. Is there recoil at that too?He literally tells Kruge when he's hanging off the cliff, to "Give me your hand!"
It's only when Kruge then uses that mercy to try and kill him by grabbing his ankle to pull him over the edge, that Kirk finally reaches the limits of mercy/patience.
I'd also point out Kirk's reaction to his own "let them die," said in anger to Spock in TUC... He visibly recoils after saying it.
Again, I'm not saying it isn't complicated mix of emotions or that it is one of straight up revenge. We certainly have seen Kirk play with revenge before ("Conscience of the King" springs to my mind). But, I'm not going to act like Kirk's motivations were totally fine or not complicated in that movie, especially in light of TUC.
Others can read it differently. But, it's not simple, to my mind.
