How does the concept of "hubris" from greek tragedy apply to the peloponnesian war?

In taking hubris to mean "excessive pride," it could be argued that this relates to the Peloponnesian War in that the Greeks refused to give up, even when it became clear that they were going to dominated by the Spartans. 

Dillion's rights were definitely violated. First of all, Dillion was a 12-year old boy, he was not even an adult. Second of all, Dillion was confined in an unhuman and dark place, suffering from cold, hunger, and thirst, and then was forced to confess. Even if he was guilty, his confession cannot be used against him because he was forced to do so. Third of all, the crime he was accused of was for burning stables and some other goods, he didn't murder someone. Dillion was tortured to make a confession, and therefore, his confession was a violation to his rights and cannot be valid.
