Were knights as good as they were portrayed?

Answer

The glamourisation of knighthood has been a steady progressive trend since the first 'tales of King Arthur', and the recognition of this fact has led many to believe the 'lashback' that there were -no- virtuous knights, and that there was no Cult of Courtly Love or Cult of Chivalry. In simple answer, knights were people, and as with people today, there are those who were the paragon of good behaviour, and those who were the worst examples of excess and cruelty.

However, if one reads texts outlining the concept of chivalry, from the period in question, it is clear that knights were -supposed- to behave in a virtuous manner, and as such, those poor examples of humanity were also poor examples of knights.
