when you are in a situation like this where the guy in the poem is, then only you can have a look at your true self ..do you lack the guts to end a life justifying it by the bad nature of the one you are going to kill or are you going to take revenge on him for somebody else who is already dead? that moment i believe is the peak of humanity ..where you can test your own morale...but when the bullet hits us, we all are just rotting flesh...those who are still standing are there to judge us but does it matter to the dead..
