Repeat Offenders

There are all different levels of sex offenders, so it is hard to determine one specific punishment for a repeat offender. However I do strongly believe that pedophiles should have the stongest punishment. I don't think they should even be let out of prison on early release, or ever if it is a repeat offense. I even believe that castration would be a viable solution to prevent them from ever doing it again. Also, depending on the severity of the crime , death sentences.
