You have to ask yourself 'What am I trying to do?' - are you a historian, or are you trying to write a gift for your family to make them feel better? If you're a historian, you have to collect all information, complimentary or not. But, you may decide to publish two versions of your tree, one for the sensitive people and children, and another with the cold hard truth included as well. For instance, I recently found out that a distant relative was sent to prison for drug smuggling. I am going to keep this information from the casual viewer of the tree, but anyone who is seriously interested in family issues, and who I think is responsible, I will share the information with. I am still not sure what to do about sharing mere rumors, and person opinions, though. I will collect them and keep them but I have yet to decide how to share them.
