Need some help searching for symbolism in All Dogs Go To Heaven.

Found a post from /pol in 1/2018 suspecting Judith Barsi was killed in ritual homicide. Claimed the films sound track has symbolism in it leaving clues as to what really happened.

https://m.youtube.com/watch?v=A0EDP9Sf4kE This was the song that caused Judith’s mental breakdown and eventually her murder. Scene context being when Anna Marie suspected she was being used by everyone around here. Given the context of the character’s mannerisms being based off of Judith herself, possible reference to how she was used and abused by everyone around her?

https://m.youtube.com/watch?v=-g710mN4YNw Pizza imagery (including the pizza falling apart). Near the end of the song, the dancing puppies form a star that turns into a circle. Innocent or deliberate symbolism?
