Oh absolutely! I never go with "inherent villainy," and agree there should always be a nuanced way of helping the audience understand how and why someone is doing something really problematic! I'm just always careful with mental health stuff - wanna be supportive. There's folks who know a lot more than I do about how to portray struggles with trauma in a respectful way (hence why a lot of folks get sensitivity readers).
Let me know if you have any questions - excited to see what you make!
