sorry friend i didnt watch movie. but i can say the people who have chakra at heart level feel emotions intensely so they are ready to do anything. and the above i wrote is not psychology.
Brainwashing, no other types of education but the one that you are in, parents telling you to only do what your country tells you as they have done, lying about what is happening elsewhere and many other things will make people do what they are told by their country. Many times food, money and shelter won't be given unless you do as you are told no matter what. Then there are countries that force their citizens to kill others or their families will be murdered.
suffering is not to a single individual it is to the whole, all the people. people fight as all being scared of the unknown. no need to include parents, religion and others. money matters when a person is frightened. their is only single event and people including me and all are not rightly involved in it
