An approach like this tends to increase enmity and ill feeling towards each other among all people. A person may cause some harm to another unintentionally and perhaps without any fault on his or her part. It is also possible that an individual who is seen as the perpetrator of the harm has not caused it at all. But when the attitude of the people is to retaliate and take revenge in equal measure, the party harmed initially will inflict similar harms on the party supposed to be the cause of the harm.
