@The girl whose a nerd I don't want to force my opinion on you, therefore I do want you to read the mahwa and get your own impressions on her. Additionally, the manhwa adaptations frequently deviate slightly from the original novels. So perhaps she will turn out to be a decent character after all. But as the book goes on, the more I despise her. However, she does appear to be a decent character in the manhwa who is looking for retribution.
And if she truly carries out her sister's advice, then her sister is proven to be correct. Because, logically speaking, she murdered her sister's husband, took her place as queen, and rendered her helpless. In a past existence, Isabella had every excuse under the sun to exact revenge on her. So she acted. And in her subsequent life, she simply displayed hysterically wicked facial expressions. I'm not suggesting she's an excellent person or anything, but if the criteria for the MC are set too low, Isabella is unquestionably more demanding than Ariadne.
