There is something to be said about soldiers or law enforcement personnel who band together in order to accomplish great and necessary things on behalf of their task masters. This is all to the good when the overriding purpose is to serve the people and their countrymen appropriately, so as to protect the homeland and society, thereby to make for a better world.
On the other hand, when soldiers band together, and are under the wrong leadership or the wrong mission, we find that it is far easier for those that are part of that band of brothers to slip into doing the types of negative things that they would in all likelihood they would not do on their own, such as rape and the wholesale annihilation of civilians or unarmed enemy combatants. That is to say, those who believe that their loyalty must at all times be to the group, and thereby discount their moral and ethical obligations, have forsaken the good for that which is wrong.
Indeed, those who are under armed fire or the intense pressure of life and death are going to see the team that they are an integral part of, as of supreme importance, which thereby lends itself to that team, if not directed in the right direction, being susceptible to doing the types of horrible crimes that society would not countenance if awake, but in many a case society does countenance, by simply not giving any credence to the stories so generated or ignoring such, which thereby signifies that because nobody is held accountable, this thereby does not resolve what should be and needs to be resolved.
When we look at human personality, it has to be understood that peer pressure and the feeling that we cannot let ourselves down to those that we either respect or are part of a group with, encourages people to do things that they probably would not do, but because of that peer pressure and also in conformance to what appears to be occurring by others, as either seen or believed in, lends itself to people embracing that which is inimical to their good character, and once that line is crossed for the first time, it thereby becomes easier for it to be crossed again and again.
This means that soldiers and police officers need to be periodically examined by internal affairs, or something akin to it, to root out problems, so that what is occurring that should not be occurring can be rectified, before it becomes even more ingrained or worse. Because the bottom line is that regretful actions are taken far too often by soldiers and policemen, that need not be happening, and would not happen if there was a more robust response to deter them from doing the types of things which are damaging to their psyche, to their being, as well as to society. This is the salient reason why there are so many soldiers who suffer from Post-traumatic stress disorder (PTSD), because once a soldier finishes his tour of duty, and thereby disbands from their band of brothers, they are left ruminating on what went down, and that which is morally reprehensible leads to endless regrets and a very troubled mind and soul.
