For example, an enemy of the village might have planted false memories in her head about Naruto being a threat. So, she starts abusing Naruto as a result. Also, it could be a story where Kushina is trying to push Naruto to be stronger in a very extreme and wrong way, believing that tough love in the form of abuse will make him a great shinobi. This could lead to a complex exploration of the relationship between mother and son in a very dark and twisted context.

In a fanfiction where Kushina survives, she could play a crucial role in preventing the Uchiha massacre.
