Oliver Twist is definitely a character to be admired. He has strong morals and a strong loyalty to anyone that befriends him. Nevertheless, in recent times, his character has come under criticism from some who find it unbelievable that someone bought up in a workhouse could not only be that innately good and naive but so well-spoken. Though they have a point, Dickens purposely made him this way so that his criticism of Victorian society would be easier to swallow for Victorian readers.
One of Oliver's most admirable qualities is his ability to survive. Despite his size and sensitivity, he always finds a way out of tough situations. For example, he runs away from Mr. Bumble's funeral parlor. In this sense, his naivety and willingness to believe in the best of people are an advantage. He is twice caught committing a crime and both times the victim of the crime takes him in them into their home, even nursing him back to health. Nancy appreciates Oliver's good nature to the point that she risks her life to warn Oliver's guardians of Bill Sikes's intention to recapture him.
