I think Dopey might be a symbol of the child victim. I have reason to suspect it based on other symbolism I've seen in possession of satanists — they do like to use the story of the 7 Dwarfs to suggest pedo-sexual rape. I've mainly seen it with the other dwarfs being the "adults" and Dopey being "the child". Not certain if this symbolism extends further than the instances I've come across or not.
