"Oh I didn't actually save the little old ladies when their nursing home burned down. I just made their life a bit easier for a little while, they still all died because they were human"
Is not analogous to this:
"I decided to donate one of my kidneys to make someone's life a little bit easier for a little while".
I am donating my other kidney to a child (1 year old with nephrosis). In any case he is living the rest of his life with this condition. I am doing this to minimize the risk of rejection during childhood. There are living people with this condition (since being babies) who are 40 years old and have families.
