It's good for everyone but you. Think of it more like having kids, but instead of passing on your nature/nurture, you pass on your exact personality and memories. From everyone else's perspective, you're now immortal, the same way your bloodline has a shade of immortality ("you sound just like your grandmother," "he looks like his father," "we've passed this family tradition down for generations"). Unfortunately, the mortal being that is you will still die, or at least remain mortal (subject to Ship of Theseus arguments).
