So even a martial artist (a master) can be scared too during an armed robbery?

Brief story:
Last year when my friend and her fiance were getting robbed at home by 2 armed men, this was her fiance's reactions:
He held her in a very tight hugging position, allowed the burglars to take all they want, gave them their wallets and froze in fear. Even though he's 6'2 and a professional martial artist, just the fact that they had guns scared him too much that he didn't want to try any moves nor put my friend in danger. If they had been unarmed, he could've easily taken them out.

Is this also a normal reaction for even a professional martial artist? He got so scared that he froze.
