Hitler was not insane thats an very ignorant comment. Many people define insanity by someone possesing a mental state short of community standards. An unbiased view of insanity is someone who is in a mental state in which he is defficient at survival ie someone who choses an option of self degredation because they do not fear getting shot in the head for example. Evil is the biggest human opnion, is self satisfaction at the cost of the pain of other evil - if yes why?? There is no universal law that deams good and evil (excluding religion) rather its the opinion of man or more so the community at large. Generally people consider genocide evil and in Hitlers case particularly selfish; a fuel for the german war machine. Than again eugenics has an upside too. If disabled people are killed that is an act of evil. To promote the birth of more disabled children (whom will suffer in life) initself is also evil. In hitlers case he was inelligent but adleast 9/10 peoples moral standard deams him evil.
