In the UK the sex offenders register is used to prevent such people working with particularly vulnerable groups. Otherwise, they are 'back in the wild' once they have done their sentence

I mean, they could still work at non-childcare jobs, or at least can here in Canada.

In general it's a good point, though. Westerners in particular seem to want their cake and to eat it too. Execution and indefinite incarceration are both inhumane, but they also don't want a guy who's openly a rapist anywhere near them in any context. Locally, reformable people are most of the prison population, but I do wonder what I'd do in the shoes of somewhere like El Salvador.
