How did the actual behavior of the nights differ from the ideals of chivalry?

The actual behavior of knights often deviated from the ideals of chivalry, which emphasized virtues like honor, bravery, and protection of the weak. Many knights engaged in ruthless warfare, prioritizing personal gain and power over noble conduct. Additionally, instances of betrayal, greed, and the mistreatment of those they were supposed to defend starkly contrasted with the chivalric code. This gap between ideal and reality highlighted the complexities of medieval society and the human flaws that influenced knightly conduct.
