Once again, I reiterate my point that the west lacks a proper philosophical/spiritual toolkit for these types of discussion.
If you are interested in the subject of good and evil, I would recommend the author Gen Urobuchi. One most westerners will be able to pick up, easily, is the Psycho-Pass series. It is a cop drama, but so much more than that, as it is the distillation of millennia of philosophical discourse and theory into a single series. Do not bother with season 2 (The Kamui arc) as it is just a marketing addition.
From there, I recommend Fate/Zero. This is more of an existential theme, but deals heavily with the concept of 'family', fate, and the nature of hope/miracle. It's a very deep series that plays with ancient history quite a bit.
Puella Magi: Madoka Magica is more pertinent to the discussion you are trying to have, but most people don't understand animated media as being capable of portraying serious existential concepts, so the prior two are primers to show that Anime =/= Cartoons. Even many Shonen, the equivalent of serialized Comics in the U.S., often get deeper and more involved than the western counterpart. If you want to know why your children are flocking to this medium, it is because it has a substance not found within the western outlets.
Madoka Magica deals with the concept of selfishness and selflessness. It is a more subtle theme, and I can launch into a long analysis of it, but the idea is rather simple. You are granted any wish. Any wish you can think of. In exchange for this wish, you get super-human powers and have to fight against witches threatening to destroy people - they cause suicides, unexplained illnesses, etc. So - where do you sign, right?
Yet, if magical girls are born from wishes, then witches are born from curses. If you were, say, to wish for a piece of cake - what happens when you eat it? It's gone. No more cake. Perhaps you should have wished for more? The inability to fulfill a wish becomes a curse - or, in most cases, you were actually wishing for something else. You wished to give someone a cake so they would thank you or see you differently - but, of course, that is not guaranteed.
When played out to their logical opposites and extremes - who is "good" and who is "evil?" When the most selfish wish collides with the most selfless wish…?
Could there be a third party to all of this - something both "good" and "evil" would equally abhor?
These subjects don't fit neatly into the western view of morality and ethics… And our insistence on binding these characters to our labels cheapen the discussion. While "Teddy-bear Lucifer" is a hilarious take on Kyuuby, its values and ideals are something radically different from what we classify as "evil" - yet somehow even more horrifying than the depths of selfish desires.
Humans used for food… Where did they get that idea?
Another fun Anime along similar lines is Kill La Kill (the name is a play on words as Kiru is the way Japanese are taught to pronounce "Kill" in English, yet Kiru means to cut). The symbolism of it is more nuanced to Japanese history and customs (the red thread of fate, amaterasu as the sun goddess, the names of places associated with Oda Nobunaga, and the use of kanji in names that represent taoist dragon-gods), but many of the themes transfer.
Although Kill la Kill is a bit less focused on existentialism at the personal level and deals a bit more with the broad concept of fate and human nature. "Listen well you pigs in human clothing, for that is the reality of this world."
"People do not live for the sake of clothing. We will be the ones to decide humanity's future."
Everything about the show is built on symbolism. The red thread of fate is what makes the clothing the characters wear - the greater one's role in society, the more of their clothing is made of this thread, such that "god robes" are made entirely out of it. Thus, the rebel group "Nudist Beach" is a hilariously appropriate play on the theme of people rejecting fate and seeking to be humans, rather than 'pigs in human clothing.'
I mean, sure, there are brainless serial productions in anime - but who do you think is running the underground manga translations and picking the good ones (well… Mostly). There is a reason why Japanese and Korean "cartoons" are translated at a much higher rate than those of any other nation. If you look at where we have Marine bases, it makes a lot of sense. If you look at chan culture and how it came about… It makes sense.
I suspect some of our nightshifters are actually responsible for funding/commissioning a number of manga/anime works - but that is based on some stuff I can't verify. There are a lot of shadow games going on out there.
