Most people's right and wrong is based in feeling, sometimes principles converted into feeling. There being no right and wrong is not how any human has ever operated. There being no objective right or wrong is mainly an intellectual fancy because there are still feelings like guilt and love which determine actual morality. You would have to have no emotions to have no morality, and in that position, you would have no motivation. Even psychopaths have reasons they do things.

tldr: right and wrong are feelings it is impossible to operate without those feelings

that is it, if you started from the baseline that all human have the same feelings which is obviously not the case. How would we even have a legal system based on what you say?

>law = right and wrong
The guy felt like killing. He did good in his mind. Laws are based on the prudences of the times and other complexities. But, laws vary from country to country, and of course there is a general law across the world (ex. theft is wrong), but that's not right or wrong in an objective sense. There is probably no externally defined right way to be or live.
