The moral of the story, the essence of the film itself!

***SPOILERS***

Is that socially awkward men who can't get their selves a are woman are better off leaping to their death's off of a high rise. Notice how the two other characters had women who cared for them and were attracted to them. Elijah had nobody, he couldn't even last 45 seconds with a prostitute. Because he couldn't get a woman he wasn't fit to fight for his country and not even fit to live so he had to die. So for all of us guys who struggle mightily with the ladies, we are done. Better make your preparations now. It's over soon.
