Would you raise your child to be better than you?

i.e. if you knew there was something that you did in your life that was self-admittandly bad, would you try to keep your child away from such? For example, some parents will go outside or away from their child so as to not transmit the idea that it's an "O.K." thing to do.

Would you be able to critique yourself accurately and honestly so that you could teach your child to overcome the pitfalls you may have?
