Rapist father

A father is responsible to care and protect his family but there are still some father out there who will abuse their children and even worst rape their own flesh n blood daughter.How could they do that? In UK a father had been put behind bars for life as he had rape 2 of his daughter which led to 19 pregnancies.The rapist son so is ashame of his father attitude had tried to commit suicide at the age of 7 because he don't like his family.He can even says that he cannot remember any happy moment that he had with his family all this while.Because of the way the father had acted this had made the who family terrorised.I am sure that his children will not forgive him as he had acted worst than an animal.For example look at a monkey,it will protect and take care of it baby from danger.How could a father rape his own daughter? This is not logic at all.Anyway is it good after all to put this type of person life behind bars.
