Why keyword cannibalization is a problem?

The thing is that, Google won’t know which page is the most relevant for a specific query if all title pages wish to rank for the same term.                                            

 When Google will crawl your site and will see large number of different pages being “relevant” for the same keyword. Then, Google will have to face a problem to fetching those pages the one that seem to be the most relevant, valuable to the query.                           

Conversion rate: why wasting your time on different pages with the same keywords if one of these is converting better? You should focus your efforts on one of these pages instead of spending energy on lower-converting version targeting the same traffic.
