These soldiers are

generally classed by society as sociopaths, people that have
no problem killing others of the same species. This is similar
to the way the immune system sends out killer T -cells to kill
cancerous or viral cells entering the body. The other 95% of
cells in the body are not designed to kill, instead they are
designed to help sustain life.
What the 95% Rule tells us, is that in violent conflicts of a
self-defence nature (eg. street fights), 95% of the people are
going to react in exactly the same way. As in warfare
between nations, the same rules apply to a small conflict
between two people, or any situation that the brain sees as
contentious. This is a war in microcosm -a small war. So
95% of us, when faced with conflict, are not going to want to
be there, we too are going to become conscientious
objectors.
