It would be inaccurate to categorize "most people" as universally selfish and uncaring about the emotions of others. People are diverse, and their behaviors and attitudes vary significantly depending on cultural, social, and individual factors. Some individuals may indeed exhibit selfish behaviors, while others are compassionate, empathetic, and considerate towards the emotions of others.
Human behavior is complex, and people's actions are often influenced by a multitude of factors, including their upbringing, life experiences, and the cultural and societal norms they are exposed to. It's essential to avoid broad generalizations about entire groups of people and instead recognize the diversity of human nature.
Research in fields such as psychology and sociology often highlights the presence of both self-interested and prosocial behaviors in human societies. While some studies suggest that humans have evolved to cooperate and be empathetic, others indicate that self-interest and competition can also play a role in human interactions.
Ultimately, it is essential to remember that every person is unique, and it is more accurate to evaluate individuals based on their specific actions and behaviors rather than making sweeping generalizations about "most people."
