Were the First Nine Makkot Deadly?

The tenth plague is known as being the harshest and most deadly. What about the first nine plagues- were they deadly, too? Patterns are apparent in the structure of the plagues narratives as presented in the book of Shemot. Some plagues include warnings, and some include explicit an explicit separation between the Egyptians and the Israelites, but these elements are not present in all of the plagues. Why are there discrepancies? What is the purpose of the presence or lack of a warning or separation? We compare and contrast the different opinions of the classic commentators as we approach these questions.
