There was a female nursery worker who sexually abused children in her care, Plymouth.
But i get your point.
Perhaps rather than ask for the death penalty, we should be asking "How did this happen?"
How did a man abuse toddlers in his care for many years, its a closed environment, he should never have been allowed to continue his vile abuse, where are the checks? what concerns were raised and then not acted on?
Sure we could hang him but it wouldn't stop this type of abuse by others.
