Am I wrong to gloat??

This week at my job was interesting to say the least.  One of my co-workers made a BIG mistake. There are three of us in this office and she has held a deep dislike/hatred of me for some time. Our third person is relatively new and young. She is a very friendly and out going person.There are multiple family connections of one type or another to others in the office workers here. One of these other workers started a rumor about our young lady and one of the male management members...... and my contentious co-worker chose to participate in this. Big mistake.......as the manager found out about the rumor and there was a meeting with him, the president of the company and my immediate boss. There was some chewing a$$ going on.  Anyway it was real quiet the last two days and I kind of enjoyed it. Our young lady was very upset and now she is no longer being spoken to either. I told her she did nothing wrong and keep her head up. And me?..........I was happy to see the guilty parties get all the mud they were slinging thrown back at them......so am I wrong to gloat?   There is no room for this kind of behavior, I don't care who you are. This should have been left in the jr high days.  Really , who starts a rumor about someone who can fire you????  DUH!!!
