I can't really speak for what I would actually do once I had the power of a god- the ability to reduce an act such as murder down to writing on a piece of paper would *have* to change me, massively- but as I am now, I would push the world in the direction I feel most appropriate. Research worldwide political happenings, respond with deadly force.
I mean, there is such potential for good in this evil artifact- letting it go to waste, ignoring the power to change the world? That, my friends, would be truly criminal.
...And, yeah, I'd probably end up benefiting financially as well. So sue me- We're all greedy fuckheads, when it gets down to it.
