I liked it. I had to do an essay almost exactly like this just last week for English, it was on who is to blame for Romeo and Julliet's death, and I said the fighting families but...I like your idea better. That it was love that caused it. And yes, while you didn't go into that much detail on it, because you also suggested that friar lawrence, lord capulet and benvolio could be at fault, the idea is strong and it's there. I liked it, well done.
