Why does the other guys fights the outsiders?

In many narratives, the "other guys" fight the outsiders to protect their territory, values, or way of life from perceived threats. This conflict often arises from a desire to maintain control, preserve cultural identity, or respond to aggression. Additionally, the struggle can symbolize broader themes such as belonging, loyalty, and the impact of external influences on a community. Ultimately, these fights serve to highlight the tension between the established group and newcomers.
