Power eternal life, or the simple fear that they might be needed again oneday though in truth I don't really think any became vimpires (Dragonborn aside due to the vimpire lord), but Morvath or something like that was a vampire hunter until he was beaten and infected by a vimpire then he became just like them, the Champion could have decided to help the count of skingrad and become a vampire. at the end of the day Bethesda makes it so the thought of cannon is entirely yours, if you believe they are the same person reborn then that's your free will to think that as while no proof is there to confirm it there is also no proof to deny it, for me I like to think they could all be alive or preserved somehow awaiting a time (last ender scrolls game bassed in Tamriel)  where they will be called upon again lead by a new hero against a new great evil, some stuff like that we all know it's more than possible for Bethesda to come up with something like even a return of the dwemer and they threaten all of tamriel, nice way to end the tamriel series before finally starting in Akavir or something.
