This quote to me means that after something has happened, more in a negative way and someone else has witnessed what you have done and you try to hide it. That person still knows what you have done in the end and it will come back to haunt you. It is how black mail is developed between two people. When someone asks what happened and you lie about it repeatedly that person that actually saw what was really going on can or may use that against you. I believe this is also where the quote "if you can't say something nice don't say anything at all" came from. If the truth is going to hurt the people you love, common sense is that society is going to lie about what actually happened. For example, you fed your best friends fish too much while she was out of town and it died, and when you tell her what happened you explain it was "natural causes" but your other friend that was with you tells her what actually happened. Now something that was not originally that big of a deal became even worse because you lied about it instead of owning up to her mistake. "A truth with bad intent". That alone to me means that if you were the witness to that incident and you decided to tell the other person what actually happened in hope to hurt them or the person that lied in the first place. This happens to everyone at least one time in your life, I think at least. Not everyone is going to point out the truth for the good of the person receiving the lie. Not everyone is going to try to make the best out of the situation but to take advantage of it. I'll be honest; most of the drama that takes place in high school is because of this. Using the truth as an advantage or to use it as blackmail so the person who is lying will be obligated to what the other person wants you to do in order to stop them from spilling the truth. But you also have to take into consideration that it would depend on the situation of what they were lying about in the first place.
