I like to do things that I want to see myself. With 'Defending Your Life,' I wanted to see some aspect of death other than angels and the thing that 'Ghost' was about, because that didn't make any sense to me. So that's the reason: it fills a hole.
Attributing to anything or anyone more good than God has attributed to them is not a positive move, nor does it mean that you have done them any good. A single grain of truth is preferable to a bumper harvest of false imaginings.
