The dimensions in which the g-dly plagues hit the Egyptians left them without any power nor desire for any immediate 'revenge'. One might argue revenge against whom, though? G-d? These supernatural wonders that occured during that time were way out of league from the things that goyim later on acused Jewish people for during our galut in europe. Egypt was powerless in the face of the Ten Plagues.
However, as already mentioned, once the Plagues subsided (the tenth and final one, the death of the Egyptian's firstborn), it didn't take too long when Pharaoh and an army of his set their way to 'annihilate the Jews' in gentile, Japhreth fashion. But it didn't work that time, didn't it. :p
What I'd like to emphasize is that Jews did in fact die during those times. Not through Egyptian's hand, though.
'Then followed the ninth plague. For several days all of Egypt was enveloped in a thick and impenetrable veil of darkness which extinguished all lights kindled. The Egyptians were gripped with fear, and remained glued to their places wherever they stood or sat. Only in Goshen, where the children of Israel dwelt, there was light. But not all of the Jews were saved from this plague. There were a few who wanted to be regarded as Egyptians rather than as members of the Hebrew race, and who tried, therefore, to imitate the Egyptians in everything, or, as we call it, to assimilate themselves. They did not want to leave Egypt. These people died during the days of darkness.'

Plague 9. If you like this answer, I will search for the exact Torah verse (on mobile so it's a bit clumsy). If not, I will delete it (as it's a personal answer and that isn't something miyodeya likes - sources are the way to go)
