Long time ago I read a confession on "secret confessions." A lady wrote about taking advantage of their niece. She was feeling proud while confessing that she and her husband were turning their niece against her own parents due to jealousy. The moment I read that confession I wish this couple to never be happy and when they have their own kids, someone does the same to them.
They still don't have kids, but eventually their marriage is on the edge of a cliff. That lady confessed to be successful, but they lost.
