Comments of chapter undefined of As a Villain in the Fictional World

i dont think this is how it works. If His daughter is the main heroine, the protagonist and her would meet up no matter what happen, thats the protagonist plot armor. This is a plot hole. and the MC cant kill her too since she have her own fate as a heroine. So its impossible for the MC obstruct her fate with the MC without meeting them himself or else this is just a big plot hole. Why not just straight up kill the protagonist if you leave such a big plot hole lol
