Osama is not Muslim. But he is still Evil

There is a story online here that says due to some technical reason Osama bin laden cannot be called a Muslim. So there is a fatwa against him that says he should not be called as a Muslim.

But does that make him less evil I don't think so. He is still that stick carrying, crazy walking, turban wearing, jihad video making, beard growing lunatic who want to propagate his Jihad against God know what.
