book 6 to 8

Throughout books 6 to 8 in the Iliad, I noticed that there's this constant emphasis on peer pressure, bravery and cowardliness. It seems that these characteristics often are what sets a lot of the warriors apart, which made it harder for me to choose or pick who is the antagonist and protagonist. first there's the part where Agamemnon basically calls his brother a wuss for wanting to spare a life in the beginning of book 6, then there's Hector who calls out the Achians also giving them this wussy title, then there's Diomedes helping out Nestor alone etc. These books are simply full of constant back and forth with bravery, cowardliness, peer pressure and betrayal.
