( If you think about it, Vriska must have had a tough 13 year of life… I mean, her spider mom makes her makes her capture/kill other kids so that she can feed her. That must really fuck a person up inside, especially considering the fact shes just a kid. It doesnt excuse her actions obviously. but its still sad to think about ::::( )
Honestly learning more about Vriska has made her a little more sympathetic in my eyes. Because damn, I bet the reason why she has the robot arm is because the spider munched on that. So it was literally a kill-or-be-killed scenario.
She did what she could to survive, and she became warped because of it
