Why does gemora record this?

 Sukkah (56b) It happened that Miriam the daughter of Bilgah apostatized and married an officer of the Greek kings. When the Greeks entered the Sanctuary, she stamped with her sandal upon the altar, crying out, Wolf! Wolf! How long wilt thou consume Israel's money! And yet thou dost not stand by them in the time of oppression! And when the Sages heard of the incident, they made her ring immovable and blocked up her alcove.

Tosefta (Sukkos 04:13) Bilgah's ring is for ever fixed and his window closed, because Miriam, the daughter of Bilgah, apostatized and married an officer of the kings of Greece, and when the Greeks entered the Temple, Miriam came and struck the top of the altar, saying to it, “Wolf, wolf, you have destroyed the wealth of Israel, and have not helped them in the time of their distress!” There are some who say that because he delayed to take up his watch, and Jeshebeab his brother came and took his place, that he is excluded for ever and Jeshebeab included for ever. Those who are neighbors to evil men receive no reward, save Jeshebeab, the neighbor of Bilgah, who received a reward. 

Avos DeRabbi Nosson (01:06)“Do not bring the foot of the arrogant upon me”: This is Titus the wicked, whose bones would grind in the grave because he would raise his hands and then strike the altar with them, and say: Locus! Locus! [Latin for “the Place,” i.e., “the Omnipresent God.”] You are a King, and I am a king! Come and make war with me! How many bulls have been slaughtered for You? How many birds’ necks have been snapped for You? How much wine has been poured out for You? How much incense has been burnt for You? And yet, You are the one who destroys the whole world! As it says (Isaiah 291–2), “Oh Ariel, Ariel, the city where David camped! Through year after year, and the cycle of festivals [I will assault Ariel, and there will be groaning and sighing].”
