Would you be with your relative that you don't get along with at the end of their life?

If you have a sibling or parent that you absolutely can’t stand, don’t get along with and haven’t spoken to in years and you find out they are in the hospital with just a few days to live, do you spend time with them? Or do you just let them die alone? This happened to someone I know of and it made me sad that this person had three brothers that didn’t get along with each other, so they left their sister to die alone rather than risk running into each other.
