That was a fairly short lived, but volatile thread, wasn't it? Xior just sort of swept in like a hurricane, then vanished....
I think in a lot of ways Hitler was pushed beyond the brink of his being able to cope, personally and professionally (as the power head of the Nazi regime). I doubt there was one single factor that made him who he "was", but like all of us, a lifetime collective of experiences, disappointments, joys, failures and definite control issues. The psychological factors that made this man tick, we'll never know for certain, but can only surmise.
