Was My Father a Bad Man?

The question is a serious one and not a rhetorical one. I hope that some readers can shed light on something that has puzzled me ever since the book, The Da Vinci Code, was published. It was brought back into focus for me today when I read some literature about Our Lady of Good Success, the Venerable Mother Mariana de Jesus Torres. The literature stated that, according to Mother Mariana, "Our Lady prophesied that at the end of the 19th century and especially in the 20th century Satan would reign almost completely by the means of the Masonic sect."

Wikipedia shows the Masons in a different light, as a social organization. I cannot summarize the whole article here for it is quite long, but you can read it for yourself: Freemasonry. Apparently, people who were considered good and moral and all that wonderful kind of stuff, like George Washington, were members of the Masons. Where I grew up in Maine and New Hampshire, the Masons were considered to be community leaders with good morals. Most attended church. From the Wikipedia article, the central statement for me was the following: "Freemasonry's central preoccupations remain charitable work within a local or wider community, moral uprightness (in most cases requiring a belief in a Supreme Being) as well as the development and maintenance of fraternal friendship – as James Anderson's Constitutions originally urged – amongst brethren."

So, I don't get it. My father was a Mason. Was he a bad man? Does anyone know?
