If you even have a very slight feeling that something bigger is going on in our universe than what is observable I would always do what is kind to people.
I would always bet on the forces of kindness and goodness.
It's the right decision even if you don't believe in anything, it's simple reciprocity, you are kind and generally people will be kind back. It makes for a better environment to live in. As long as they aren't war zombies.
