Besides Tuvax being eliminated in voyager
TNG: The First Duty, where Picard lectures Wesley. Such a powerful scene.
“The first duty of every Starfleet officer is to the truth, whether it’s scientific truth, or historical truth, or personal truth! It is the guiding principle on which Starfleet is based, and if you can’t find it within yourself to stand up and tell the truth about what happened, you don’t deserve to wear that uniform.”
For me it has to be the end of In The Pale Moonlight
So I will learn to live with it…Because I can live with it…I can live with it.
Computer – erase that entire personal log.
Gives me chills

I love the contrast between these two themes
“It’s a faaake!”
I was going to post the same thing.
I lied, I cheated, I bribed men to cover the crimes of other men. I am an accessory to murder. But most damning thing of all, I think I can live with it. And if I had to do it all over again, I would.
Just… god damn it hits hard. Also Sisko’s change in tone turning the final “I can live with it” into a question.
Don’t worry Captain, it is logical. The needs of the many outweigh
The needs of the few
…or the one.
“I lost a brother once. I was lucky. I got him back.”
“I thought you said men like us don’t have families.”
“I was wrong.”
Two words: salamander babies.
Happy Threshold Day!
This is my personal favorite moment. It’s a distillation of pretty much everything I like about Star Trek in one conversation.
Pretty much the entirety of Waltz from DS9. https://youtu.be/R2HY50xw3WU
Dukat usually appears like he’s trying to be a good person, despite all the terrible things that happened under his watch. But this episode breaks that down until he finally stops lying to himself.
For me, it’s This
Captain James T. Kirk : All right. It’s instinctive. But the instinct can be fought. We’re human beings with the blood of a million savage years on our hands, but we can stop it. We can admit that we’re killers, but we’re not going to kill today. That’s all it takes. Knowing that we won’t kill today. Contact Vendikar. I think you’ll find that they’re just as terrified, appalled, horrified as you are, that they’ll do anything to avoid the alternative I’ve given you. Peace or utter destruction. It’s up to you.
im scarred for life from when dead spock was sent to the genesis planet
they killed spock
i have to think anything that can effect me like that had to be great
The death of Edith Keelor.
The end of Darmok was pretty epic.
Man, now you just trollin’.
I get a laugh out of Sisko doing a silly child’s dance in Lethal Candyland, in that episode of DS9 when they make first contact with a bunch of gambling aliens. “Allamarane! Count to four! Allamarane! Then three more!” It’s those little moments in Star Trek where respected actors humiliate themselves for the sake of the plot that are just so great to watch. See also Armin Shimerman as the silvery announcement box in one of the early TNG episodes.
“I’m a doctor, not a bricklayer.”

To me it was when the episode ended with Picard having been assimilated by the borg. When I was watching it it was way too late, and I had a flight that I needed to catch in the morning. I pulled an all nighter because I needed to see what happened next, despite knowing that the next 24 hours would be spent in transit.
To this day, Picard turning towards the camera all borg’ed up right before the end credits is the biggest cliffhanger I’ve ever seen.
Now imagine having to wait until next year for that next episode! Worst cliffhanger since Boba Fett flew off with Han Solo!

I just love the DS9 episode “In The Pale Moonlight”, it shows that the federation can be just as capable of being bad guys as the other factions.
