Is Rota kinda bad? Please spoil me about this

she is
she married varia's murderer a.k.a the big bro of the cunning wife of the emperor by their father order.

she enjoyed stepping on her sister like how their father has teach.
but she isnt a major villain, just annoying chick on the side (so far from what I read)
Leo will smack out of her tiny brain in the next chapter. (▰˘◡˘▰) and the next next chapter too (づ￣ ³￣)づ
