People are the way they are because it is the way they have adapted to survive in their world. You can accept them or reject them for it, but it makes little sense to try to change it. People are they way they are because it is the way that works for them. The same way you are.
I gave up the idea of being able to change other people a long time ago. As much as you perhaps don’t understand why people are they way they are, it is not your job to.
You can try and help people, make them aware of the negative things they are doing but never try to change.
