1. Bad user experience
2. Loss in traffic
You can put 301 redirect for this page to some other page or to your home page.
Visitor will avoid to come to the page if it is directed to 404 error page. It is better to redirect 404 error page to home page or any other page.
It can't be denied that there will be bad user experience if we don't redirect the page.
However,there will be two duplicate URLs with same content if we rediect the ERROR page.
In this way,our site will not get the TrustRank.
Also,google will think lowly of the quality of your content.
