Most people view the practice of loving-kindness, or metta, as a personal decision rather than a rigid moral requirement. Metta, which has its roots in Buddhist tradition, emphasises developing kindness and compassion for both oneself and other people. It is not usually required as a moral obligation, yet it is advocated as a way to create a more caring and peaceful community.

One of the four brahmaviharas, or sublime states, in Buddhist teachings, along with compassion (karuna), sympathetic delight (mudita), and equanimity (upekkha), is metta. It is believed that engaging in these states can help one grow spiritually and personally, resulting in increased inner peace and wellbeing.

Nonetheless, in certain situations or groups that place a high priority on these principles, the practice of metta may be considered as a moral duty. A Buddhist monastery, for instance, could place more emphasis on developing loving-kindness as a component of moral behaviour and spiritual practice.

Ultimately, one’s personal views, societal traditions, and the particular spiritual or ethical framework they adhere to may determine whether they consider metta as a moral responsibility or a personal option. In any case, cultivating loving-kindness may have a significant positive impact on one’s own wellbeing as well as the harmony of society.
