Imagine there are two Whumpees. Whumpee 1 has been there a while, Whumpee 2 has just arrived.
Whumpee 1 is blaming Whumpee 2 for the torture they experience for breaking the rules.
Whumpee 1 has been with Whumper so long they believe the rules are pretty much just common sense really.
Whumpee 2 is desperately trying to convince Whumpee 1 that what Whumper is doing is wrong.
Whumpee 1 cannot be convinced and begins to harbour malice towards Whumpee 2.
Whenever Whumpee 2 breaks a rule and gets punished, Whumpee 1 is always there to rub it in after the fact, who knows, maybe victim blaming is just the way Whumpee 1 manages to subconsciously retain a semblance of control.
Whumpee 1 loves Whumper, Whumpee 1 is obedient and will do anything for Whumper. It's Whumpee 2's own fault they're so defiant.
"Oh yeah, you really shouldn't have done that! What are you? Stupid? Any sane person would know to NEVER do that around Whumper."
"Well maybe if you were a little more obedient they wouldn't have done that."
"Well its your fault for making Whumper upset! You need to be nicer!"
"I told you not to do that, but you went and did it anyway! I don't feel bad for you."
Whumpee 2 begins to hate Whumpee 1. All sympathy vanishes from them. They look forward to the day where Whumpee 1 finally slips up.
One day, Whumpee 1 does slip up and gets punished by Whumper.
And dear god, after the physical beating, they got the verbal beating of a lifetime from Whumpee 2.
But, instead of the bitter responses and glares Whumpee 2 was expecting. Whumpee 1 agrees.
"Yeah, I deserved that, I was careless. I won't let that happen again!"
"I'll make sure to try my best to never disappoint Whumper!"
Its the kind of stuff Whumpee 1 would say motivationally to themself. It disturbed Whumpee 2.
And for the first time in a long while, Whumpee 2 feels...a little bad for Whumpee 1...
