If god is all powerfull and all good then why does suffering exist?

(copied from debate a christian)

Please don't say free will etc., there is nothing intrinsically good in free will.

My previous post got removed, since apparently there was not enough support for my argument, which I don't understand, but here I will explain it further:

If (a) god made humans only capable of good or if he didn't create the possibility for suffering (as in it's just not "physically" possible), that would only be a good thing, so for the god that the bible describes, there would be no reason not to create the world like this. Therefore he can't be all powerful or all good.

Also: people don't have free will, I can't fly or teleport even if I wanted to, so my free will is obviously limited, so why not limit it in a way where I can't do harm?
