Even Mandodari was a good rakshasi. Despite of being Ravana's wife, she always used to advise her husband to return sita back to Ram, as she knew the outcome would lead her husband into the darkness of death. A devotee to the Lord Shiva; always praying for her husband's good life and a good mother. I still remember when Indrrajeet was going to do his final combat with Laxmana, she told him that following the virtuous and dharma's path would eventually give him moksha.
