Star Trek: Voyager1995

[2371-Janeway intends to change her future for the benefit of her crew]

Captain Kathryn Janeway:
If the temporal anomaly doesn't kill them, something else will, the Borg, telepathic pitcher plants, macroviruses - the Delta Quadrant is a death trap!

Chakotay:
What about the Temporal Prime Directive?

Captain Kathryn Janeway:
To hell with it!

Chakotay:
With all due respect, it's a little presumptuous to think you have the right to change everyone's future.

Captain Kathryn Janeway:
From what I've seen, they'll thank me.

Chakotay:
All you've seen are bits and pieces. You're not getting the whole picture.

Captain Kathryn Janeway:
Really? Just what am I missing?

Chakotay:
It's not 'what', it's 'who'. People like Seven of Nine, a Borg drone, who'll become a member of this crew, after you help her recover her humanity. Or Tom Paris, a former convict, who'll be our pilot, chief medic, and a husband to B'Elanna Torres.

Captain Kathryn Janeway:
That angry woman I just met?

Chakotay:
She's gonna be your Chief Engineer. Two crews, Maquis and Starfleet, are gonna become one; and they'll make as big a mark on the Delta Quadrant as it'll make on them, by protecting people like the Ocampans, curing diseases, encouraging peace. Children like Naomi and Icheb are gonna grow up on this ship and call it home. And we'll all be following our Captain, who sets a course for Earth and never stops believing that we'll get there.
