Of course not. Hitler's plan to exterminate the Jews was based on theories of race and religious history and political conspiracy that were not only false, but absurd. A false justification is no justification at all.
Hitler and many millions of Germans (not to mention millions and millions of others still) would have lived a much better, more enjoyable life, with less anger and paranoia and disappointment degrading their happiness, and more vicarious joy and contentment and friendship uplifting it, if Hitler (and anyone who might have replaced him) had embraced a life of reason and compassion instead of hatred and delusion. Any sane, rational person would prefer the latter outcome, to what actually became of Hitler and his beloved Germans.
