My brother, temporary gain will cause permant damage.
think about the Nazis; Hitler moblized the Germans by creating imaginary enemy (Jews), he had blamed Jews for every problem German had and committed the most barbaric and savage act in human history and also invaded other neighboring countries, including France, and they looted so many property from other countries and they build their country and their military. I am sure at that time Germans used to enjoyed and had endless lexury, but their happyness did not end long. their supermacy mentality vanished when they were confronted by the Red-Army of Russia.
Most of the nazi generals, SS members, including himself paid the price, still now German is condisered cursed.
Now Melese and his gangs doing the same thing. They creat an imaginary enemy (amhara) and moblized tgirans and controlled the country. As you said they are looting so many properties from other part of Ethiopa and building their area, and most of the Tigrians also enjoy and have endless lexury as germans used to have; however the time would not be long, those barbarians to pay the prcie, as Germans do.
I am sure those tribal war lords will be bring to justice when their time come and will have a speedy trial and hung publicly for their crime as the Gestpo leader.
The only problem is an individual like you, being the instrument of those tribla war lords indirectly or directly, by hating other tribles.
you are right he might have destrioyed Amhara supremacy and land. But look he is the most constructive person as far as Tigrai is concerned. His people are indulging in all sort of previllage, happiness, investiment and Tigrai development at the cost of Oromia and Amharai. Is he not the best politician for his own people???
