If i had a Conversation with Brom

If i got to have a conversation with Brom it would be very long and i thinnk that he would get irrated with me for asking so many questions. Brom was my favorite character in the book until he died but i would ask him about why he would never tell Eragon is past life.I would want to know how he killed Morzan and all of those Forsworn Riders when he didn't even have his Dragon. I would want to know whty he liked Morzan so much, because Brom was always so wise in his time in the book and why he couldn't see that Morzan was no good. I would want to know a lot of things but my main question would be why he would never tell Eragon about hes PAST.
