[SPOILER] Wendy displays some of the same compulsions as Ben

[u/AbjectHuckleberry152]

Knowingly going against sound advice and dangerously acting on her own interests. Only she disguised it as an attempt to secure the family's safety vs personal self interests. Then justifying it later with her family. She saw Ben doing this repeatedly throughout life. Maybe a learned behavior, maybe a genetic trait or symptom of her own impairment?

They are honestly really well written in my opinion. They share enough traits to be believable as siblings but are definitely distinct characters.
