Is group fighting a common enemy a positive or negative thing?

Group fighting against a common enemy can be viewed as both positive and negative. On one hand, it fosters unity and solidarity among individuals, promoting collaboration and shared goals. On the other hand, it can lead to increased aggression, division, and the dehumanization of the opposing side, potentially escalating conflict rather than resolving it. Ultimately, the impact depends on the context and the underlying motivations driving the group.
