revenge in upper egypt

There is a story about a man who used to live in upper Egypt then he left and came to work here in cairo and in a specific holiday he went back to his home in upper
Egypt to find out that his house is set to fire also his car is broken and his brother is dead then he discovered the reason behind it his father killed someone from the other family and other family took revenge by killing his father and his brother. Who has the right to kill an innocent person just because he is a member of the other family , Revenge is ugly and horrible more than you can imagine it creates wars , crimes , vendettas. Revenge appeared in the old age before even Islam arrives so people got used to take their right by their own hand because they were not guided to the right path. Revenge was part of their morals and traditions till it developed and became a must in upper Egypt because if they didn’t take revenge they will face a lot of problems. Although some people think that revenge is an honorable thing to do in fact it's pointless because it contradicts with all the religions and the legal system of Egypt and it affects the whole society and people psychology.

Why would the opponents seek and always want to take revenge?.
They think that taking revenge is transforming shame into pride and complete satisfaction. The feeling of weakness comes to them when they feel Ashamed of themselves when they live without taking their revenge.
These feeling of helpless might result in low self esteem and identity crisis
