JC did indeed sing a lot about death, also judgement, redemption, the darkness in his soul et c. In his years as the black-berobed Cash he found a wide audience. Some British Goths showed a new respect. One was Head of Science at a high school. At the first departmental meeting after JC died, the Science man called for, and got, a minute's silence before business.
Kitsch, JC was not.
