i like that how karna,bhsim,shakuni etc.are standing on their vows.Secondly,i also likes that after knowing that karna is not sut putra but a kshatriya he does not tell anybody about it and also he did not insult MATA KUNTI.i liked the role of KARNA in this serial because he is very loyal to his friendship,he is very powerful but always respect elders and gurus and also he belives in karma.
