Decent people can never understand the evil that lurks in the minds of others.

Our minds cannot comprehend such thinking which also explains how we didn't see 9/11 coming.

And why we are so horrified at the glee exhibited by the subhumans that beheaded Nicholas Berg.

Decent people can never understand the evil that lurks in the minds of others

Perhaps we can't understand what makes them evil but we can certainly understand that it exists and understand we must be aware of the signs.
