If you are kicked in the head by a horse, your personality can change due to the physical effects.
If you drink alcohol, your thought patterns can be changed.
You are physical
It is not your physical brain that "carries on". We know that, because we can see it rot and fall apart.
However, we also know that our personalities are intrinically related to the physical brain.
This then leads to talk of a soul. A soul is not a copy of my brain or it would be useless as soon as I died because it would fail to capture my personality. If I got kicked in the head and my personality changed, how would these changes be reflected in a soul? will the soul suddenly change too?
So my real personality cannot be "carried over", the best scenario you can offer is that a copy of me "a soul", reads the state of my personality at my moment of death, stores it and then it somehow something happens to this carbon-copy of my personality.
You see, the whole concept of an afterlife is emotionally driven **** wittery. I know you think you're being insightful and musing on deep concepts, but really you're just regurgitating cultural vomit from primitive cultures that suffered from relative information poverty, illiteracy and engaged in burning witches. Why are you cherry picking cultural baggage? Witches have just as much evidence going for them as afterlives.
Here's the story, your personality is based on a physical metastructure that is going to suffer integrity damage at some point in the future and then your personality is going to cease to exist. If you're struggling to imagine what that's like, consider what the world was like before you were born.
