Would you be willing to sacrifice your welfare in order to save someone else? It depends, probably not.
For example:
If you heard someone shouting for help inside of a burning building and the firemen had not yet arrived, would you be willing to suffer severe burns to try and save their life? Definitely not. I don't even know this person. I'm not going to risk serious damage to myself to save someone I don't know.
OR
If someone needed mouth-to-mouth resuscitation but they had a cold sore, would you be willing to contract HSV-1 to save that person's life? I will update this after learning about HSV-1, probably not.
Edit: Oh no it's herpes ew. I would call the ambulance maybe? I don't know in that sort of situation
What do you value more? Minor/Major aspects of your welfare, or another person's life? Minor/Major aspects of my life.
Would your answer change if a family member or loved one's life was at stake? Yes, but depending on the severity of the damage to myself.
Would you be prepared, or even able, to live with the guilt if you decided not to save them? People are able to deal with a surprising amount of guilt, or even are able to ignore it altogether.
If you don't think that you would feel guilty about letting them die, why do you think that you wouldn't feel guilty about it? Because I don't know them, so it wouldn't have an impact on my life. I would probably end up rationalising it shittily such as "Oh millions die every day it's not a big deal".
