He was put into a device that changes the universal constants of the universe and it not only survived, but it seemed like it enjoyed the experience. They have considered nuking 682, but seeing as it survived this, it is more likely that it will just adapt to it and then use these adaptations to kill us all.
 
173 was the first SCP created on the wiki. Due to its IRL historical status, it is more likely that in a fight between 173 and 682 that the writers would decide to decommission 682 than decommission 173.

@megaman295  
Wut?

If it doesn’t go something like this, I will be disappointed.

C’mon, rip her dress off. yeah… that’s it. this is hawt. o3o

@ze  
Then why is 682 still there?…Seriously though, how unkillable he is, is ridiculous, I guess him actually being scared of 173 takes some sue points off though.

@Background Pony  
What the SCP Foundation would probably do is, as you said, contain or attempt to contain Discord. From there, they would then consider how much they could learn from experimenting on Discord vs the expenses of containment. If the expenses outweighed the benefits, they would proceed with decommissioning. If they could convince Discord to join them, they would probably keep him around.
 
The real reason most reality benders are decommissioned is because most reality benders in the SCP universe are Mary Sues, just plain stupid or are self-inserts and thus most writers want to get rid of them.

From My Little Pony to an animated Dynasty.
 

@ze  
Eh, fair enough, still I would think one would take more precedence and be a bit trickier to catch.

No no no. This flailing around scratching is a terrible way to fight. The proper way to fight is to wait until she’s walking home and brain her over the head with a tire iron when she idn’t looking, or failing that punch her in the exposed throat.

@ze  
Can somebody tell me WHY i have never seen this vid before?

@SeraphimDawn  
Or cat noises.

@King Sombra  
I do believe you mean this

@Background Pony  
I’m guessing you don’t know the SCP Foundation’s usual response to reality benders.  
Dr. Clef already took out Discord.

Need some Epic Battle music!

@Klonoahedgehog  
You devil you. :P

and then movie was a unanimous success.

INTERNET FIGHT

@ze  
Nah, they’ll be too busy with their world’s version of a reawakened Discord.

@SeraphimDawn  
Then the crown falls on her butt, turning it into a princess.

Now tear the dress off and throw hher in the mud!

@Itsthinking  
It be funny if Derpy suddenly and literally butts in to this fight, knock the crown off.

@ClownDicks  
whoops my bad
