Yes. Look at the whole picture, realize you are claiming God to be all powerful, and realize that he must intend the horrible suffering in this world to exist. Sure, there is good as well, so maybe he is a little benevolent, but that doesn't change all the nasty stuff he made for us and subjects us to. A perfect creator could have avoided the sadistic diseases that face us.
Did he? Last I checked we had lots of incurable diseases. And last I checked it was human scientists that came up with the cures we do have. And even if he did send both the problem and the cure, what does that tell us exactly? That he wanted to make us suffer, but only for a while? If he wanted to cure disease, then why did he put it on us in the first place?
No. These are perfectly fair questions. They are all we have to go by to judge this creator you claim to exist. We don't know exactly what his reasoning was that led him to make innocent children suffer through disease, but we do know he did that, if we presume he exists and is all powerful. And before you say it isn't for us to judge him, because we don't know everything, realize that you also judge him and deem him worthy of worship, and call him just and good, etc. If we presume an all powerful creator then all evidence I see points in the other direction.
