Pesachim 82: Gleaning Halakhah from Narrative: Nadav and Avihu and Their Father's Korban

If the Korban Pesach is rendered impure, on part of all, how is it than burned? And how different personalities or economic standings have impact on who brings the wood to burn it. Plus, what in human nature we protect and protect against, and the potential to misappropriate public funds, even though we're talking about the holy Beit HaMikdash. Also, if the Korban Pesach or a portion thereof was taken out of Jerusalem - that too has to be burned. [What's What: Kodshim Kodashim/Kodshim Kalim] Plus, learning korban practice from the biblical offerings on the day of establishing the Mishkan, when Nadav and Avihu died and Aharon doesn't eat from the sin-offering that he brought that day (and the ensuing complicated rebuke and defense between Moshe and Aharon). And the implications of notar (leftover korban) and pigul (wrong intent). Note that the daf does not tell the story of Nadav and Avihu, but without knowing it, understanding Aharon's behavior is that much more puzzling.
