Brazil effectively abolished the death penalty in the 19th century when the king D. Pedro II denied pardon to a slave that was posthumously proven innocent. He was so horrified to have sent an innocent man to his death that he pardoned every single death penalty in Brazil afterwards. Death penalty was officially abolished by the first republican constitution, several decades later

 

 I understand why some people want the death penalty but it’s impossible to not have innocent people also die. One innocent death is one too many for me so I can never support the death penalty. 

 100%, and that would be if wrongful convictions and corruptionwere rare. They are sadly very much not.
