Religion and Faith as Weapon/War in God's Name

Religion and faith are two different things but in balanced coexistence they have purpose. One without other will have positive impact.Faith is believing and personal relation  with mighty Creator, believing in different things without real proof to be truth. Faith is also known as trust and closely connected with emotion. There are a few stages in faith(intuitive-projecting, mythic-literal, synthetic-conventional, individuative-reflective etc.) and every stage depend on person. Faith as such is usually in relation with religion and it is common in every religion because there could be religion without faith but no faith without religion.
Religion is specific life style combined of cultural heritage and specific actions all in order to live according our faith. That specific life style could be quite different from one religion to other or even in one religion during long period of time. Why is that? Because of different circumstances and social exposed to different social problems.That is why some nations very closely use their religion as synonym. Religion was life stile which helped them to resist occupying or wars for instance.  Religion ensures believing system common for specific group. Usually believing system keeps one group all together and makes it different and specific in relation with other similar groups.
As I said religion is mostly association of ethnic and national roots, combined with faith it could be strong weapon good as well as bad depend on use. Most people is very easy to manipulate that their believing system is the real one. Some religions have believing system for each day in year  what one believer should and should not to do during day. So as you can see if there are rules for every day in someone's life it is very easy to manipulate with such individual. Religious beliefs tend to be part of personality.
Due to alienation in modern and secular societies people tend to be part of something like family, certain social group and most of people even find them as part of religious group. Be welcomed, be part of something gives feeling of belonging somewhere and feeling to be loved. And that is quite normal thing everyone wants to be loved and everyone miss it. And that is the moment when someone from any group it is not necessary to be religious group going to use for some own needs. Our believing system with strong faith that we are in right is very sensitive moment and sensitive moment for every person. It is one very brief explanation why religion and faith could be very powerful  weapon in the world, and the war in God's name in fact is the war for someone's interests, God does not want from us to kill each other but to be free of non necessary religious rules because most of rules have no deeper theological or spiritual meaning.
