Well I reject the notion that the human body or its remains has anything to do with the soul. The soul moves on. I believe that animals have souls too, although not the same as humans. I saw a soul leave a dead body once, so it seemed to me at the time. It went as if with a purpose, into another dimension or something. But the body was like a useless thing afterward.
“Now may the God of peace Himself sanctify you completely; and
may your whole spirit, soul, and body be preserved blameless at
the coming of our Lord Jesus Christ.” - 1Th 5:23
The Bible has this and a lot more to say about the body, soul and spirit. Whether alive or dead, I will honor and respect my body, spirit and soul.
