I'm sorry, I don't live in the US so maybe I don't really understand, but why do these websites even exist.
If someone is a dangerous sex offender, he shouldn't even be in the streets. If not, then he committed the crime, did the time, why does he need to be punished for life?

In fact, he didn't "do the time", because part of the punishiment is a life-long listing in the sex offender registries.
If you'd rather, you can think of it this way: sexual offenses in the US carry a mandatory life-sentence, with some of that sentence being time spent in jail.
Last I knew, it was justified under public safety. People who had already been sentenced and served their time in the past had been listed on newly-created sex offender lists. Court ruled that it wasn't a punishment, so it couldn't be considered ex post facto punishment. Wikipedia indicates the case that decided this was Smith v. Doe, 538 U.S. 84 (2003).
