Dude was Jewish, so I don't think cremation was his choice. They used it to hide something.

"Jewish law and tradition consider cremation as destruction of property. Jewish mysticism, or Kabbalah, also holds that the soul does not immediately depart the body. Rather, it slowly leaves the body as it decomposes; cremation therefore is considered to cause pain, even after death."

In keeping with Islam—I mean Jewish tradition.
