If these things are signs then this might explain why so many Christians including yourself believe the end is always gonna happen in their life time. From a historical prospective I can't think of a time period when governments didn't run a muck in different countries? The united states does it now and before them it was the British, Germans, Japanese, Spanish, french, Romans and Persians. Also i'm sure they told their constituents one thing and did another. So to answer your question, yes there are tons of things humanity needs to work on morally. Like most things progress takes time and has to go through the painful trail and error process.
