I havent finished the game, but im wondering from the message boards:

why do you kill pomab? please, try to keep spoilers to a minumum

Reasons to kill Pomab:
A. It's fun.
B. He needs to learn humilty.
C. Who doesn't want to kill him?
D. It's fun.
E. He's not, as you say, a nice guy.
F. It's fun to kill pompously little airhead shopkeepers like him

oh, I thought it was required to beat the game. I thought maybe he was really a demon or something

It is required, but you asked for no spoil. He's attacks you at end of the last chapter, right before you fight the demon.

I guess they did that because do u remember in the begining where pomab calls you dirty adventures something like that i dont remember maybe they put him because if anyone was pissed at him and wanted to kill him but wanted do buy from him this was your chance to get him back. It was fun seeing him blow up thou very amuzing

yeah that was fun, i rather enjoyed whipping his pompous arse.

It wasn't as fun as I had hoped.

I would like to see what happens when you kill him right off the bat! I think the town turns hostile on you.. but I am unsure.. if you can get away with it, that would be interesting.
