No its Seska in State of Flux. She says it to Chakotay befor leaving his quaters. "You can't defeat me. You're too weak."
(I can't tell you how many eps I went through to find this. Excellent quote!) Alien Hallucination (called Trajis) speaking to Seven in "One". "Actually, I was having trouble sleeping. I could use some company. "
Janeway to Kes in "Tuvix" "They're cutting an access route through the hull. Evacuate Deck 3 and seal it off."
Good fake out! I thought it was "Deadlock" but nooo, its Chakotay in "Fury". "That didn't give us the right to murder civilians!"
Semi psychotic Captain Braxton to the Police on 20th century Earth in "Future's End". :-) Early culture has its demons. They embody the darkest emotions of its people. Giving them physical form in heroic literature is a way of exploring those feelings. The Vok'sha of Rakella Prime believe that hate is a beast which lives inside the stomach. Their greatest mythical hero is a man who ate stones for twenty three days to kill the beast and became a saint.
NBG011, Meld was an inspired guess, but the wrong season. Exodus is very close, but LeadHead is correct. My fav line of the scene follows, but it would have been too obvious. TUVOK: Such fables are necessary only in cultures which unduly emphasise emotional behaviour. I would point out there are no demons in Vulcan literature. CHAKOTAY: That might account for its popularity. LeadHead, don't forget to offer up a quote.
Later season? Janeway says this to B'Elanna at the end of "Twisted". (I'm afraid I cheated on this one, so I shouldn't give the next quote. I'll leave that honor to whomever finds the season 6 (?) ep that you might be referring to.)
Twisted! That's the episode I was trying to think of. I knew Janeway had said that in an early episode. As for it being from season 6.......I'll Guess The Haunting of Deck 12.
