Applying the Rule of the Inverted Tarot Card...
You know, in a deck of tarot cards, the meaning of an upside-down card is reversed -- same as the card itself.
For a person such as Osama Bin Laden, whose sense of basic human decency is so obviously inverted, I would say that the Tarot Card Rule also applies to the meaning of his name.
In other words, the ordinary meaning of the name of "Osama" (when tagged on Bin Laden) is reversed and becomes: "evil-wisher; extending malevolence towards someone with good intentions".
