its normal if you are a true believer to hate evil acts and any harm to innocents..and love God and love to do good deeds and help others,,,etc..this is the real signs that you follow the true path..and therefore obey God laws..and if you did all of this nice things or even as much as you can..you will not be in doubt about God in your life,,actually you will be 'sure' and you will chose to be wise instead of feelings all this anger..
anger is not nice feeling at all..and God want from us to be fair and honest and wise,,and even Merciful..not to be angry all the time and 'imagine' this is nice in the sight of God..hope you reconsider this important points.
No. You probably without even realize it, have an anger against yourself. Psychoanalysts see this everyday in their offices. Anyway this can be easily cured.
As for the gods, they are just men creations ( not the opposite)..
