What was the purpose of all those long destructive wars Wayanes and Shabia waged?

Some people were mislead and  thought that the TPLF and the EPLF were fighting for higher cause, but the true purpose  these criminal organizations  wagged long wars was because their leaders wanted to gain power in order to loot.

The destructions these criminals caused during the wars, and the damages after they came to power with their lootings,corruptions and racist policies  is immense, and  the exact magnitude still needs to be calculated.

But the biggest damage of all is they hindered the  progress of the country. That why these criminals are also responsible for the backwardness, poverty and displacement of  the people.
