For the purposes of this trope, either attitude counts as a valid example. Some works and characters will draw a distinction between chattel slavery (applying principles of property law to humans and other sapient beings, allowing them to be formally owned, bought, and sold) and other systems of forced servitude such as debt bondage, Indentured Servitude, Prisoner's Work, serfdom, etc., while others will consider all of them equally heinous and dismiss such distinctions as hair-splitting. In short, these works or characters treat slavery as a Special Kind of Evil.
