As Christians, it’s natural for us to associate bloodshed with redemption. In light of the Gospel, the idea seems intuitive. That bloodshed can bring about redemption, however, is an unusual idea, which is revealed to us gradually as the Biblical narrative unfolds.
I appreciate your observation about the "passovers" (plural). I posted my seminary days paper on Academia.edu just touching on his subject. There I proposed a chiastic structure covering Exodus 1-15 and how the life of Moses is typical of Israel (and later Christ). One of the parallels in that structure is between the bridegroom of blood episode (which is otherwise oddly placed in the narrative) and that of the first Passover.
