Violence is a necessary part of combat, and that is something every Marine understands when they step on the yellow footprints that first day of bootcamp. Few people crave it outright, but they all accept the very real dangers endemic to service, even when they join during peacetime. Once the war is on, though, it becomes necessary to embrace the danger and the violence and lose your sense of self for the greater good. But really accepting your mortality is on some level  the easiest part. Acknowledging the mortality of your brothers and sisters is another thing altogether. After all, protecting yourself is only valuable insofar as it helps you protect others. Right?
