What is Casca´s attitude toward the people? How do you know?

Casca thinks that the people are fickle and easily deceived. Casca remains onstage with Brutus and Cassius and tells them that the three shouts they heard were because Antony offered Caesar the crown three times, but he turned it down each time. Casca then says that Caesar swooned and fell down with his mouth foaming at the lips. (Caesar was considered to be epileptic, called the "falling sickness".) When Caesar awoke, he begged to be forgiven for his infirmary. Casca adds that the people forgave Caesar and worshipped him even more for turning away the crown.
