the evil is always stronger than the good?

Today, in the office. There were good and bad news. The good one is what I have wanted and tried to realize for months, so the news was a kind of reward for me. The bad one was not my fault at all, the fault of the managers and the shame for the company. So I don't need to blame myself, but the bad news was so shameful, disgusting and quite destructive for the job I have taken charge of, so it have made me feel really tired and blue. It seems that the shameless people always have power for they care nothing, nobody. I sometimes really hope that some terrorists would blow the top floor of our office building, really! :(
