Your quote (if that's what it is) proves its own falsehood (unless it's a partial quote): it's a quote after the fact. (He might have said something like: "I don't want people to say that..." etc, as Hitler was very concerned with his rôle in history.) Though it was certainly Hitler's intention to kill all Jews, he already might have known at the time this would be an impossibility - if for military reasons alone; the Final Solution (Endlösung) envisioned by the Nazis would always be limited to the Jews under their control.
Apart from that, the "quote" isn't Hitler's style of speaking or argueing. (It would be helpful, though, if you had an actual source - but, to be true, I doubt anyone exists.)
