ELI5: Why is it that it seems easy to control our limbs from moving, yet difficult to prevent our eyes from glancing at something we don't want to look at?

It's in your DNA, you are wired that way.

Seeing something negative is a survival trait.  To see something unpleasant or dangerous = increased ability to deal with it.  So even if you want to look away, something gross or violent or threatening, you'll feel compelled to look at it.

So for that same reason, since it's a survival trait to be able to control your limbs, your DNA wires you to tend to have good control of your limbs.
