Some want to die, while some others want to stay alive

There is a different attitude toward army, depending whether one wants to die or stay alive and healthy. Suicidal may want to die so much that they go abroad as volunteers. As soldiers they are different from those whose primary goal is to defend country and good living conditions. 

Collected from a big group, like for example Asia, there may be many who are not motivated to the local life, but may volunteer to fight a war. But such also means that they believe that locals too want to die, and so the misunderstandings may be fatal.
