Which is exactly why they are justified calling her a lady of the streets. Just because you are one thing doesn't eliminate you from the other. She seems to think she can get by with doing prostitute (as shown when she lost her shoulder bag and offered her body to her former husband (?))People who critique Eva by calling her a lady of the streets (etc) don’t seem to realise that Eva may be flawed, but she is human. She has lived a life of wealth and greed supplied to her by her father and not from her own merit. She does not fully understand what “love” and affection truly means, but Tenma is the closest she has to that - and she knows this.
Eva is driven by the man she pushes away (because she is not used to the love he gives) but simultaneously finds herself coming back to him because of her loneliness.
Eva is the definition of a tragic character.
