Why are humans able to use the elements of harmony for evil?

[Midnight Seashell 206]

Since the beginning of Equestria girls the elements have been corrupted and used for evil.

 

The results were:

 

Sunset Shimmer wanted to take over Equestria and she got corrupted by the element of magic.

 

Sci-twi wanted to understand magic but she couldn't control it then she turned into Midnight Sparkle.

 

Gloriosa wanted to keep her camp by whatever means she could and then this happened.

 

Perhaps their desires were so strong that it corrupted the element(s) and turned the holders into a physical manifestation of their desires, sort of like how gamma rays turned Bruce Banner to Hulk who is a manifestation of his anger.But what do you think?

Gloriosa never used the elements.

Remember what Sunset Shimmer said "what happens when you bring an element of harmony into an alternate universe/dimension" obviously that means something bad happens magic is now in that world and it is corrupted. The elements are bonded to the spirit rather than the person/pony themselves is how I see it. So if there is a human version of the element of loyalty it can work is what I'm assuming.

 

I guess the real question would be why it worked for Sunset Shimmer? Remember it didn't work for Spike or at least it didn't work with what they were trying to do at the time. Maybe if he wanted to shoot a laser it could have worked who knows.

 

Magic is strange and not exactly streamline especially when it is in another universe. Maybe that's why it worked on Sunset Shimmer. If she wanted she could have put it on as soon as she got it from the castle but she chose to wait until she got back into the human world. Hmmm....

I view it simply as the fact that like a gun, Magic and the elements of harmony themselves are only tools to be wielded. It's the person who uses them that determines if it's evil or good.

 

Though how Sunset knew something like that would work, I'm still puzzled at. She didn't have much time to read before Celestia caught her, nor did Celestia have much knowledge of the realm as she readily admits, so there couldn't be that much written down involving interactions in regards to cross dimensional crisis and powers o.0

Well I believe that the elements of harmony reflect the emotional state of the users, such as when the mane 6 were corrupted in season 2, they were unable to use them.

My headcanon is that the Elements of Harmony amplify the user's emotional state, such as how Sunset Shimmer's desires for power and revenge were overtaken by the Element of Magic which became much more powerful in a world without magic.  Thus leading to her being corrupted and turning into a demon.

While Sci Twi and Glorisa weren't using the power of the Elements, they were still using Equestrian Magic that they didn't understand. Their lack of understanding how the magic worked, along with them being under great emotional stress at the time, lead to them losing control over their source of magic.

I wrote a topic about "How Equestrian Magic Works in EQG world" that goes into detail about the climaxes of the first 3 EG films. Read that for an better answer.

 

Simply put, "In the Equestria Girls world, if Magic isn't used with good intentions, it can be twisted into something bad."

The elements of harmony are manifestations of emotions thus I think that anyone can use them so log as they possess the will and correct emotion to the element they use the crystal forms of the elements are simply mediums for conducting the emotional energy just as horns are necessary for unicorns to use most equestrian magic, as such it is my belief that if a human goes to equestria and finds such a medium they would be able to use certain types of magic the same goes for places with strong magical residue such as the cave at the camp or the school as for why the elements are usually corrupted by their human users that is likely the wide diversity and strength of human emotions when compared to the ponies of equestria who seem to have limits on the strength and diversity of their emotions
