There are many legends and stories so it is unknown to which one are you referring to. However, he is usually described as a just king who values everyone as equals, hence the myth of the round table. In another myth, he supported Sir Gawain's almost certain death because it was an honorable thing to do and if he hadn't done it he would be a liar. He always valued honor, truth, justice, and anything positive like that.
