Heh. You want all my thoughts, or just enough to be disturbing?
I'd go back to feudal Japan and appear constantly as their god. I'd take a break for a few hundred years and then, right around the time of Hiroshima and Nagasaki, I'd show up and inform the US that they couldn't drop the bomb there (while transporting their planes to someplace odd like Berlin). I'd tell the Japanese to surrender anyway and buddy up to the ol' US so that they could leech their culture and technology like it is today. After that, again with the constant showing up and "blessing" multitudes of my favored people.
I'd appear in three different avatars: one a beautiful, manly man who spoke Latin; one a beautiful, womanly woman who spoke Japanese; one a corpse burning in green flame who spoke German. Of course, people would mentally hear me in their own language while also hearing the three of me make my pronouncements.
I'd abolish arachnids in any form, and anything that masqueraded as one.
I'm sure there's more, but I can't remember right now.
