I'd like to think about this and reply in more depth later, but the first thought in my mind is "no". Mainly because death is not the only cause of tension in stories. Hypothetically, a character could be brought back to life, but their marriage to their wife could still slowly crumble into nothing. Inserting necromancy into, let's say, Fitzgerald's work, would be bizarre and would somewhat ruin the tone of the story, but would not eradicate the sense of tension in the relationships and the downfalls of the characters.
