WAR - Manipulation of Some Powe Hungry People

These days I found War is happening between Russia and Ukraine. The main reason behind this WAR is still unknown everyone thought of their own idea or speculation about it. I always believe this WAR is no matter how big and small is the reason some power-hungry people wanted to prove that they are right and others are wrong. 

Actually, I heard a very good theory on Right and Wrong. There is no Right and No Wrong the only thing that exists in the situations and consequences that matter. This situation drives the whole nation a man a woman or some group of people about to take the decision. Now somebody will tell me "Killing" is wrong correct how can it be right or not wrong? So it is important to see the situation which tends that killing happened now if someone commits a kill for his/her safety then how can you call that person a killer. Nevertheless, the WAR is depicted in the same situation. 

Now there is a good term in Marathi "Doghanchya bhandanat tisarycha Laabh" meaning in between two fighters or the enemy the real fruit goes to the other person. Now everyone is taking benefits from this WAR situation how can you call this Right or Wrong. 

We as mankind/human beings need to understand at the core level the important factor to be considered is "ME" how can I be the person which leads to greater goods.
