There's no such thing as karma.
Just look at the world, one glimpse is enough to see the obvious.
It's our conscience we should care about. It's the only thing that distinguishes us as beings. And to know that none of us is perfect. Don't be too proud to apologize when you error, say when you're sorry and know that there are never too many thank yous.
Be your better self, one day at a time. For your conscience. Because at the end, it is all you got. No pseudo karma points in the world will ever save you from yourself.
