It’s OK for people to volunteer even if it’s just to add credence to get into uni or for any other reason. It’s a means to an end.
Everyone wins.
It furthers the individual in their ultimate goal of getting where they want to be, and for those receiving voluntary help, such as in a hospice, they are nearing the end of their lives and have more to concern them than who is feeding them or holding their hand in their last moments - just that someone is doing it.
