I really don't like that so much of the fandom depicts Pinkamena as a sadistic psychopath. When I saw Party Of One I didn't see an insane pony with a mind to kill, I saw a mare who's heart had been broken after being convinced that the people she cared for most in the whole world had stopped loving her.
I don't believe Pinkie Pie is capable of hurting anyone, depressed or no. And that is my opinion.
Anyways I don't know what's gotten into me, all of the sudden I'm having the urge to draw sad ponies. :/
