Sin,does it still exist?

I have been  wondering why the term sin has almost died out in our language and I think  for many of us who were brought up in a very strict version of Christianity it became too painful  for us to think about it.
We were made to feel ashamed  of our failures so much so that we abandon the whole idea of sin.
We don’t know as children that it is very difficult to live without making mistakes and our emotions run away with us so that we hurt other children….
But now looking at the world as it is,maybe it would be better of more adults admitted making dreadful mistakes.And we know  free will may not be as free as we think.But if we accept we do sin then it makes us more tolerant of others around us…If we were perfect it might make us self righteous and judgemental which to me seems a perversion of religion.Yet this is happening  in the world today.
I have read that it is very hard for Catholics,even lapsed one,to be able to  have a successful psychoanalysis because the conscience is so harsh.We cannot easily alter it.
So it is not surprising we don’t like the word sin.
It is interesting that being thought of as sinners means we are quite powerful,If our errors are caused by human weakness it is more painful to see ourselves as weak and vulnerable yet we are.We all need others.
