What is humiliation? Why do we get angry?

According to Collins Dictionary, the definition of humiliation is the embarrassment and shame you feel when someone makes you appear stupid, or when you make a mistake in public. When we are humiliated by others, especially in public, we are very likely to get angry and want to get a revenge. Why do we get angry, especially when we are humiliation in public? If we assume that we always behave rationally and even our emotions behave rationally, then we rationally get angry for a reason when we are humiliated.

If we are humiliated but do not get angry or try to revenge, then we are afraid that we are likely to be exploited more in the future. In order to avoid such circumstance, people find getting angry and trying to revenge a more effective way to protect them from being humiliated and/or exploited in the future. Therefore, it is rational for us to get angry and try to revenge when we are humiliated. Moreover, when we are publicly humiliated, it means if we do not fight back, more people will see the chance of exploiting us and a higher risk lies in front of us, then we should fight back even harder especially when we are publicly humiliated to protect ourselves.
