Why is god to blame for suffering?

God is certainly not to blame for suffering. See, when Adam and Eve committed the first sin, the Devil challenged God. Lucifer said that humans can rule themselfs perfectly without the help of God, and the humans agreed with the Devil. So God took the challenge. God left humans alone (and he will leave them alone until the second arrival of Jesus) to deal with themselfs and see if they were right when the Devil and humans challenged God. As you can see today, man has made a mess of things. So God clearly won the challenge for his right to rule. Since the world is so bad, Jesus will come soon, which is why we must prepare for his arrival and get saved to enter God's paradise.
