Arjuna or Karna – Who was the Greatest?

Let us not forget that we have seen Arjuna and Karna from their birth to death. Naturally, we have “different” Arjunas and Karnas here. Would any reader accept about him/herself that he/she has remained constant and static throughout his/her life? That, what he/she has been in her teen days, he/she has remained the same in her 20s or 30s or 40s or 50s…? Would any reader in his/her ripe days like to be judged by his/her action of green days?
