burden of 100+ lives

The flight experience while traveling from Bangalore to Mumbai was super nourishing for my thought process. From 10:30pm to 5:00am sitting alone on Mumbai Airport, I thought about many things.

The foremost was that about the feelings of the pilot of an aircraft. The flight had more than 100 passengers. When it entered troubled regions, all the 100+ lives become a burden on the pilot’s shoulder. All this while he was carrying this weight with him but suddenly it seemed like he became the Atlas. Now he had to make sure more that each and every life was safe and secure. More that even his own life was in danger. He must have felt like a soldier in the battlefield. He was eying with his enemy (bad weather) and trying to fulfill his duty.

I wonder what would be the last thoughts in the mind of a soldier.
Does he think about his motherland and its safety?
Or just like any other normal human, he sees his death dancing in front of him?
Second one looks more human. My English teacher in school believed firmly that no soldier thinks about his duty in the last moments, he just thinks about his life. May be she is true.
Too difficult a question to find a simple answer.

Most of the war veterans suffer from sleep disorders and loss of orientation after they come back from the battle field. Many of them have accepted that they think a lot of about the killings they have done. They feel it was not justified. Their memories haunt them throughout their life.

I read a real nice line on war recently "War do not decide who is right, they decide what is left"

Does a terrorist think the same way? Does he ever feel the burden of so many lives, or he really thinks killing is his noble duty?

Is the burden on 100+ lives so heavy to carry?
