There are unfortunately cases when knowing the truth tends to make people less moral. If you discover the truth that the bureaucracy you work for tends to reward loyalty over hard work, this will probably not make you a better worker.
In fact, most of the people we consider highly moral (Ghandi, Mother Teresa, MLK) come across as pretty nutty to ordinary people. Of course you could argue they were following a higher truth. So perhaps the truth makes you more moral, but simply increasingly the number of true things you know will not necessarily make you more moral.
