Describe the role & character of chorus?

The Chorus of Elders, a group of old men from Argos, serve as a passive observer to much of the action, refusing to get directly involved in either aiding Agamemnon when warned by Cassandra that Clytaemnestra plans to murder her and Agamemnon. Nor does it make any effort to stop Clytaemnestra and Aegisthus after they emerge from the palace, bragging about the murders. Instead, the Chorus is very passive and complains about everything, without trying to do anything about it.
