You’re confusing murder with imprisonment.

@Mildgyth  
Don’t answer on my behalf! And yes I am.

You’re confusing murder with imprisonment.

The fact that at one point Chrysalis was literally singing it while her minions were ransacking Canterlot, for the sake of the song reprise, kind of sealed it.
 
And it was outright stated that ritual was localized to the valley/basin, by Daring Do herself.

@Background Pony #6ED7, @Latecomer  
We do have evidence that Chrysalis always had it in her to be evil: This Day Aria, where she admits to having dreamt of being a conqueress since she was small.
 
 
@Background Pony #9983  
For the world? No. The world is way too big for one known ritual to cause a drastic global heat wave. The greatest area likely to be affected was the surrounding jungle.

@Mildgyth
 
Ah. Well in that case, I think they’re taking this a bit too seriously.

@AC97
 
No, they aren’t.

@Background Pony #DF25
 
Excuse me, what’s your deal?
 
Are you pretending to be someone else, and you are that user? Because if you are, that’s actually against the rules.

@oddball 623A  
Certainly, I think Discord has shown that he’s dangerously unreliable.He still means well, though, and that goes a long way with ponies.
 
Chrysalis was nothing but evil before she lost her hive. Psych help might be useful, but I fear she’s too far gone.
 
Cozy is the one most likely to be targeted for reformation.She’s also the best liar of the three, though, so it will be hard.
 
Tirek escaped Tartarus on his own while in no better a state. (Which is why they really need to get some proper guards instead of some monster mutt.)

@Latecomer  
Discord turned the world up-side down to satiate his own lust for irregularity. Not only that, but he continued to routinely screw with the main cast even after he was declared “reformed,” up to and including nearly getting Twilight Sparkle and Princess Cadance killed via the Tatzlwurm. Then there was the whole betrayal when he sided with Tirek. Fandom explanations aside, the show makes zero mention of Discord having planned that one the way it went down.
 
Chrysalis was obviously mentally unstable and broken after she lost her hive. She required help via a specially tailored institution (which we know exists in Equestria) rather than a firing squad.
 
Cozy Glow was a child. At the worst, the same thing that applies to Chrysalis applies to her.
 
Tirek is the only one who there is a legitimate argument against. Either way, he was helpless by the end of the second episode of the finale. On top of which, he was helpless while he was in Tartarus, too - which Discord circumvented and then afforded Tirek the strength to become a threat again.
 
If they deserved the firing squad, then Discord should have been the first to bite the proverbial bullet.

@AC97  
HEY. LEAVE BACKGROUND PONY #9983 ALONE.

@oddball 623A  
Destructiveness isn’t necessarily the main measure of redeemabiity. Has it redeemed more malicious ones?

@AC97  
Reminder that the show has redeemed far more destructive villains than those three.

@Background Pony #9983  
Perhaps try presenting one worthy of respect?
 
I really don’t see why you’re so hung up on those three as non-murderous anyway.

@Background Pony #9983
 
Well, when you take the last three episodes into account, they’re murderous psychopaths.
 
Full. Fucking. Stop.
 
Claiming that it just isn’t them is whitewashing that’s ignoring canon.
 
Frenemies changed nothing about them. They resolved to stay evil. They were never planned to be reformed.

@Background Pony #9983  
I was being facetious.

@Smart Heart  
So now you’re with them?

@AC97  
I never said that. You’re just finding ways to consider them murderers. Maybe I’m just finding ways to consider them not murderers but you obviously don’t know me very well.

@Background Pony #9983
 
What makes you think Chrysalis wasn’t already an adult by that point? Tirek was in Tartarus, so everything was exactly the same to him until he escaped.
 
You’re grasping at straws.

@AC97  
The events between the sonic rainboom and the episode itself.

@Background Pony #9983
 
I know what you said.
 
Their lives were exactly the same up to that point as well, so there was no “alternate backstory” to justify their actions.
