You're missing the point. I "latched onto" common decency because that is what the user before you brought up as a valid reason. It was only typed for demonstrative purposes.
So the other reasons you've given are similar - it's in your best interest, and in your community's, and in the world's. Notice that that is exactly what was argued in my comment before: "Can you provide a reason to care for someone that has nothing to do with religion and nothing to do with a personal/societal gain?"
