Dude how can you respect Nazi's in the context of today? Would you respect the Tories if they managed to sort our economy by putting Poles or Muslims in work camps? I appreciate the utilitarianism however can any majority real feel comfortable enjoying wealth and privilege at the cost of a minority. In the case you espouse surely any Nazi, good father or not, paid a massive moral price if they knew the extent to which Jews were being scapegoated for the benefit of the country. As subjective as good and evil can appear to be there are values connected to goodness. Therefore if someone doesn't value honesty, justice, human rights, decency, laws etc. then they can be described as evil - anyone who then supports them certainly loses the right to call themselves good.
In response to your point on modern politicians it is wiser to look at how often they use Hitler's tactics to divide and rule. Furthermore they don't deny the problems listed but persistently underfund attempts to deal with them. The problem there is capitalism, and most likely always will be.
You seem also to assume that a person must hate someone they view as evil and that hatred should be directed only to their views. I agree you shouldn't hate evil people but that is more for your own benefit than theirs, hate is never a good emotion to maintain. However you cannot ignore the choice they make to hold those views whether it be through wilful ignorance or rationalised argument. I therefore reserve the right to dislike anyone who likes Nazi's.

I think the previous commenter already addressed Nazi's so I will address you're original question. Are we good or evil? Well in actuality I would say neither as there is no such thing as an objective view of good or bad. Both those things are subjective, or rather completely dependant on our own points of view.

That said in my personal view of good and evil the answer would be yes. We all contain the capacity for good and bad. It is up to every person to decide how they will be.
