> Do you think people look in the mirror and say “I’m going to be a terrible person today?”

Not so directly, but I do think that a lot of people don't put any effort into being a good person.

Think of the shopping cart problem. Good people return their shopping carts to the store or a cart return. Many people can't be bothered to do that.

People think "oh I'm not bad for leaving my cart in a parking spot" they think "stealing or damaging a shopping cart is what bad people do"

But they're still kinda bad people for not returning their carts. They're certainly choosing not to actively be good people.
