I think he does know about his secret
Itz a ultimate genjutsu beyond your imagination .......
oh wait ... didn't they say that nagato died or something ?

Nah Yahiko is the one your thinking of because we have found out all the bodies are corpses somehow revived back to life by the Rinnegan to my logic each having some relations to Jiraiya
but i think that pain is just self brainwashed on his rinnengan, so the one pulling the strings is the rinnengan.lol
Agreed but why is Nagato doing all of this did he go on some of kind insane rampage when Yahiko died is he emotional disturbed or to mentally weak to handle his own power
