Final answer:
The statements "I do what I want," "No one can stop me," and "I take what I want and harm anyone who gets in my way" best exemplify Ethical Egoism, the moral stance that actions are right if they promote the individual's own best interest.
Step-by-step explanation:
The thoughts "I do what I want," "No one can stop me," and "I take what I want and harm anyone who gets in my way" best typify Ethical Egoism. Ethical Egoism can be categorized broadly into two types: Common-sense Egoism, which regards egoistic acts as a vice involving putting one's own interests over others to an immoderate degree, and Psychological Egoism, the view that all human actions are motivated by self-interest, even when they appear altruistic. Strong Ethical Egoism is the belief that it is always morally right to pursue one's own greatest good.
Contrary to Ethical Egoism, Altruism is the selfless concern for the well-being of others, which is not reflected in the provided thoughts. Hedonism, is more about the pursuit of pleasure as the ultimate good, and Nihilism is a rejection of all religious and moral principles, often in the belief that life is meaningless; neither of which directly align with the ideas expressed in the statements given.
