Actually, yeah, I'm rolling with the theory that Madara had the hots for Mito, and was a fairly nice guy... But Mito went for bad boy Hashirama, who would turn out to be a massive prick, both in personal and political life.
After this, he went batcrap-crazy, and devised a huge plot spanning about 20 decades to turn reality into a huge dating sim where he can be with Mito forever.
Btw, it's not like Madara wasn't doing the hikkikomori thing for more than half of his life after the valley of the end battle. One has to wonder what was he doing all that time.
edit: Can't wait for Sasg-ay to get the spotlight again. Really, the ammount of good-feeling-love-your-country-and-village-be-loyal-to-your-army messages in the last few chapters is making me sick.
