At the end of a byzantine question on Wednesday night's program, PBS' Charlie Rose asks Karl Rove, "what makes you so evil?"

"Well I can't answer that completely," Rove replies. "I do have a theory though about the Internet. I think the Internet grants people a pseudo-anonymity that allows them to say things that they would never say to somebody in person and never put in a letter but would feel comfortable saying as accepted political discourse on the Internet, and after awhile it becomes ingrained in accepted practice."

"It seems to go deeper," Rose says.

"Beyond me," Rove replies.

The following video is from PBS's Charlie Rose, broadcast on November 21, 2007.
