It's both, but I have a feeling I would have had more time if the nurture part was/is decent. There is a such thing as learning too much about one's own existence. Although I was more severely abused when I was younger, I didn't know so much about people and the world I lived in and, therefore, was stronger (oblivious), full of pep and hope for the future (oblivious) and gave too much credit to humans on the whole (oblivious). I made the mistake of opening my eyes wider and learning how to read between the lines. Knowing what I know now is the reason why I spend a few to several hours each day when I first wake up trying to talk myself into keeping going even though two decades of persistent medical/mental health treatment has not only failed but not prevented my health from getting worse with age. Therapy tries, when I can afford/find it. I sometimes wonder if head trauma + vast memory loss will be the only thing that would keep me compatible with the wanting-to-live-and-share-the-world-with-people-who-make-me-lose-more-hope-as-the-years-roll-on mindset. I often feel like an evolutionary write-off.
