I don't know that it is possible to think rationally about things like that. It will always be a challenge for parents.

IMHO the key question is: what do you with that fear? If you let it rule you, there is a high risk of becoming such a controlling and overprotective parent that the child never gets the real-world experience that they need in order to survive.

I have seen many real-life cases of parents who were way too overprotective, out of a motivation of love and concern. But it really hurt the children because while they were kept safe, they hadn't developed a lot of street smarts. By the time they then ended up in college, they were a ripe target for predators.

Timeless problem faced by probably every halfway decent parent that ever lived.
