Evil
A Catholic definition of evil - consisting of three forms... physical, moral, and metaphysical.
An editorial from the <a href = http://www.detnews.com/2001/editorial/0110/25/a15-326536.htm<; Detroit News relating to 9-11.
And a whole web site devoted to evil and the law. I kind of like the term "depravity" rather than "evil"... evil has too many religious connotations.
