Also, maybe have a character in deep moral turmoil, who must chose between his once "diplomatic way" or a now strive for sudden survival. If he was a politician, you could have him gain a sudden realization that, his survival tactics of preying on that which is weaker or ill-abled to defend itself is much like those which he used to practice in his previous career ventures, only now he has good reason. Before, it was merely for materialistic gain, but now it is for his very life. He finds that his moral struggle was nothing more then an illusion he had created, as he wanted to fool himself into believing climbing upon others was the only way he could reach his highest self, as he never found any other way.

However, once more, he falls under the influences of greed and hatred, and resumes his aggressive tendencies in order to raise to the top. He soon, though, finds that there are others like him. That even though he stepped upon those virtuous and or passive, he soon misplaced himself, and stepped on one trying to reach the same goal. And thus, in the shadow of the night, he is murdered, to represent that the turmoil we cause upon others is the pain that shall be sent back; that often that which you send out, returns itself in. And, in this case, the greed and hatred he released returned to him in the form of a dagger.
