"Are there any advantages of hiding the truth?" Hmmmmmm, let's think about that.
Would Obamacare have been passed if the truth about it wasn't hidden?
Would Obama even have been elected if the media didn't hide the truth about him?
Would Obama have been re-elected if the truth about Benghazi wasn't hidden?
Would Holder still be in his position if the truth about Fast and Furious wasn't hidden?
Would Hil liar y be a candidate for President of the US if the truth about Benghazi wasn't hidden?
It seems that there are advantages to hiding the truth! And they are all nefarious. In the end the truth will out if it is being hidden for nefarious reasons. If it is hidden to avoid "unnecessary" pain or hurt for a loved one, that can be wrong too but I suppose like beauty each situation must be determined "in the eye of the beholder" however everyone deserves the right to be told the truth, especially when it directly affects them even if the truth is painful. Life is painful, we should always be prepared for the worst and understand that our destiny is ultimately in the hands of a higher power.
