To do his job well, an Infantry Soldier serving in Afghanistan (or any other part of the world) needs to give less than a shit about their enemy. The more detached the better. The more calloused the easier the life of a grunt becomes. I know, I have had that mindset, I have put up a wall, and cared less then I ever though possible.
The mind of an Infantry Soldier is NOT the mind a contributing, caring citizen should have. Don’t get me wrong, we have cops, and their indifference to suffering is necessary to do their job well. But for the majority of citizens, caring about their neighbor per say, is a critical factor to having a society that succeeds and thrives. Indifference to others is a breeding ground for destruction and hate. I am guilty as most, and have gone from being an 11B grunt to a citizen who struggles with my own selfishness and doing the right thing. Below is a great quote to help us re-examine ourselves as citizens, gamers and humans.
Monsters remain human beings. In fact, to reduce them to a subhuman level is to exonerate them of their acts of terrorism and mass murder — just as animals are not deemed morally responsible for killing.
Insisting on the humanity of terrorists is, in fact, critical to maintaining their profound responsibility for the evil they commit.
And, if they are human, then they must necessarily not be treated in an inhuman fashion. You cannot lower the moral baseline of a terrorist to the subhuman without betraying a fundamental value.
