Only two things can drive a man to such extremes as what Hitler did.

Love and insanity. The scary part is when someone has both.

Hatred and negative emotions just for the sake of it rarely can keep someone driven long enough and hard enough to reach such lengths.

No reasonable person who has looked into hilters life can say that he wasn’t absolutely head over heels in love with his ideal vision of Germany

And as he grew older and the drugs really got to him the insanity really kicked it up a gear. Depending on which side your in with how much he used drugs and how impactful.

No one who uses what he did even lightly stays entirely sane while under the pressure he hoisted on him self in his mad attempt to make his vision a reality.
