Are you calling God evil? Because he certainly allowed very bad things to happen to Israel when the turned their backs from Him.
Sometimes you must allow pain in order to get the people’s attention. It this case short term pain will result in long term gain ... hopefully.
Is either any of us God? No. Can any of us understand the mind of God? No.
For us humans the ends don't justify the means. Hoping for Obama to win the election by some so that it would be a wake up call to the masses would be permitting evil to happen to bring about a good. Only God thru his permissive will allow evil in order to bring about a greater good. This power is for God only, not use screwed up mortals.
