I'm not sure I'd really be either good or evil as it is all very relative.
Hitler is hated by people the world over yet there were, and still are, people that thought what he was doing was good. Likewise some people worship Gandhi, but there were and are those that hate him.
The ideas of good and evil are entirely subjective and vary from person to person. I'd like to think that I'd be a "good" god, but I know full well that should I gain such awesome power there would be a huge quantity of people that would wish for my death due to my views on all religions and the nature of political power in the world.
In D&D morality scales, I'd probably be Lawful Neutral due to my personal views on how things should be, but not everything I do would be things that are considered as "politically correct". I have a very strong moral code, but I am also very uncomprimising and strict about some things and would tend to react very harshly towards violations of what I consider as basic human decency.
