There are multiple threads like the already.

While I was facing something that can be classified as abuse in my childhood from other children and I had fantasies of horrible revenge and i still have those fantasies of revenge, nothing of that is related to guro in any way because guro is supposed to be erotic and not just hateful.

The reason why i like guro is because it is one of many things I like and i usually prefer happy guro where characters do not suffer or if they suffer they are not emotionally crushed.
