Human nature ethics refers to a system of behavioral standards that humans are born knowing. It has no relation to ethics based on an absolute power such as a god or belief system, but is based solely on what humans instinctively know as good and bad behavior.
Other ethics systems include consequence-based, rights-based, relativistic, entitlement-based and virtue-based. Consequence-based ethics is a system that relies on the anticipated outcome of an action in order to decide what to do. Through this, humans consider how the action can affect themselves and other people and make decision based on this.
Rights-based ethics is based on the rights given by a community, such as human rights, legal rights or moral rights. Relativistic rights are based on experiences during a person's life. Because these ethics come from personal experience, they vary widely between different people and are largely dependent on culture and upbringing.
Entitlement-based ethics is based upon selfish thoughts and the consequences to other people or property are disregarded. The wants and needs of the person making the decision are the only considerations. Virtue-based ethics originated from Aristotle and is based on the character and intentions of the person. Virtue-based ethics is not about social duty but instead focuses on the morals of the individual in question.
