Is It Ethical to Use What We Know?

We lie to ourselves, because we self deceive. It's very few people do bad and know it atthe in the moment,. Very people think themselves as bad people. And so what i bhutly trying myself is to apply behavioral sience on myself, and you encourage other people doing the same thing. How do we structure our own environment so that it's harder for us to stray from that path over time? Right?
