One of the tags here says “Unicorn master race”, for what, cute?

She knew enough to seek the Amulet for the power boost it would give her. How likely is it that her original source of information made no mention of its corrupting effects?
 
Also, the merchant claimed it was too dangerous to sell (until she offered him more money) which should have been a warning sign.
 
It’s absolutely possible Trixie knew nothing about the corrupting effects—but if so, I think that ignorance came from a reckless failure of due diligence on her part.

@MetaFour  
Do we know that she was aware of what the Alicorn Amulet actually was and what it did? It’s been quite a while and I don’t recall all the details of the episode.

Light Yagami says what? XD

@Ewazor  
Trixie’s odd in that she’s a victim of circumstances, but then she responds to them in exactly the wrong way and makes her situation even worse. In “Boast Busters”, the Ursa wrecking town wasn’t Trixie’s fault. But when Twilight saves the town (and Trixie) from the Ursa, Trixie responds by insisting that she’s still better at magic (somehow) and immediately running away. I’m convinced that’s the precise moment when Ponyville’s general opinion of her flipped from “Cool magician! Great show!” to “Wow, what an asshole”—and the moment Trixie doomed herself to never living down the Ursa incident.
 
You’re right that we can’t blame Trixie for anything she did while under the Alicorn Amulet’s effect. One the other hoof, we can and should blame Trixie for putting on the Amulet in the first place. For wanting to get revenge against Twilight (one of the few ponies who didn’t antagonize Trixie at all) and for seeking out dangerous magic artifacts to accomplish this.

I never meant to debunk your previous comment, I was saying de facto antagonist because she was one by technicality of the episode.

What a bunch of cute stronk little unicorns.

A protagonist is the main character of a story.
 
An antagonist is someone/something that opposes the protagonist, or someone/something that the protagonist has to deal with in order to accomplish their goals
 
In Amending Fences, Twilight is the main character, so she’s the protagonist. Her goal is to make amends with all of her old Canterlot friends.
 
Moondancer stands in the way of this goal; she doesn’t want to forgive Twilight, doesn’t want her friendship, and wants to be left alone. So in this story, she is the antagonist.
 
“Protagonist” doesn’t mean “good guy”  
“Antagonist” doesn’t mean “bad guy”

@Officer Hot-Pants  
It’s kinda hard to call Trixie an antagonist too. She was just a performer… and then she was mind-raped by the Alicorn Amulet.

@Background Pony #74DA  
Being the target of a protagonist’s attention doesn’t make you an antagonist. She wasn’t bothering anyone and just wanted to keep to herself. Twilight was more her antagonist, if anything.

So cute. Twilight clones. ❤❤❤❤

D’awwwwwwwwwww~!
 
@Background Pony #74DA  

 
She was a de facto antagonist, at best. Twi was the one responsible for Moondancer being the way she was.

@Officer Hot-Pants  
Of course she was an antagonist. She just wasn’t a villain.

*DING, DING, DING, DING, DING!*

@Officer Hot-Pants  
Moondancer, who was never an antagonist?

Twilight X Twilight X Twilight X Twilight OT4. ;D
