In Genesis 9, God gave mankind the executive DUTY to protect innocent human life, and to punish those who shed innocent human blood.
Don't blame your failure, and the failure of the politicians you empower, to do so on Him.
In the realm of Christ, man has no power, nor life, but that is granted by God. You must not know that God started all this, and He knows how it will all come out. You may not also know that in the New Dispensation of Christ, the Law was fulfilled, and no longer has an effect on the believer. Genesis 9 is not confirming what you demand, sorry.
But, most of all, you must not really believe that God allows things to happen for a reason, in everyone's life. If you did, you would not be so judgmental of those things you can't change. Instead, you would support a person who will help to lead us out of the swamp we are struggling through.
If I go to DC today, I will have to speed or get run over. If I get pulled over (and some do), I will get a speeding ticket. I better be wearing my seatbelt, too! They don't believe in unearned grace...
