Where did I say dialysis is better ?

Also idk your personal reasons for need of a transplant but common reasons for acute renal failure are diabetes melleitus, vascular disease, and immunological diseases. Many in each category have a genetic component. I wouldn't dare to pass such risk to offspring but to each his own I guess.

To grossly sum it up, we end up putting new kidneys in people who fucked up their own because they got diabetes (ok, a small share is congenital, which also sucks a lot). I don't feel like sustaining that and I don't feel guilty the slightest.
