Review Detail of FBI_B1TCH in Becoming Immortal

I've been seeing many Twillight fanfics being recommended to me lately so I finally decided to try one. I have never read the books nor have I watched the movies and yet I am thoroughly enjoying this. I didn't get lost very often at all and when I did a quick wiki search will solve my problem. Only thing that bothers me about this fanfic is the fact that the MC is a slut, fathering children then leaving them without even bothering to raise them. I understand that he's currently living in the bronze age so behaviour like this is common and he's also trying to find out if his children would inherit his abilities but the MC came from modern times, can't he be more civilized? At least be a decent father ffs!
