Final answer:
Treating others well, being considerate, and tolerating differences align with the core value of respect, as put forth by the Character Counts organization. This is supported by care ethics and Confucian principles which focus on benevolence and just practices that ultimately rest on respect.
Step-by-step explanation:
According to the universal ethical standards identified by the nonprofit, nonpartisan Character Counts organization, treating others how you'd like to be treated, being considerate, and being tolerant of differences represent the core value of respect.
Care ethics echoes the importance of such values, placing emphasis on caring and compassionate relationships, which align with the concept of respect. Confucian ethics similarly prioritizes benevolence, a value deeply related to respect through its communal and relational focus.
Lastly, justice in various ethical frameworks, including Confucianism and Mohism, incorporates the notion of fair treatment, which rests upon the foundational value of respect. Therefore, the core value in question is respect.
