Why was the treaty that ended World War 1 such a bad treaty?

It wasn't a peace treaty many would argue, since it focused mostly on blaming the Germans mostly for starting WW1, and it punished the Germans and made them pay 30 billion to repair the Allies' damages, there are several parts to the treaty, but they directly/indirectly show that the French and British wanted to punish the Germans, not to go to peace.
