Did Tom Cruise's character really need to get mad at that lady interviewer?

Including calling her a b*tch and threatening her because she was just doing her job whilst trying to get to the bottom of what really happened?

I understand that he probably didn't want the whole family matter to get out the way it did but still...

In his situation, if I was in his shoes, I would've calmly exclaimed "Sorry I don't want to talk about it" or walk out if it was getting personal, but he's like teasing her with "I'm not sure I hear a question here" and then gets rude with "What is your f*cking question" and then sits quietly for the whole interviewer but then he insults her with "b*tch" and "f*ck off" and then almost hits her physically, like, that's not very nice, is it?

Cheers.
