That depends on whether or not you consider this to be a bad thing. One of the advantages of reacting before becoming aware of the action itself, is that in an evolutionary sense it can be the different between survival and extinction.

It might be less apparent nowadays, but anyone who's ever dodged a car almost hitting them, will be very glad indeed that evolution has made us react before realizing what we were going to do.

This doesn't mean we can not freely decide what to do though. But one should wonder, what's the point? If you decide to consciously ignore fight or flight-reflexes, it will probably just kill you.
