For me, it really help me with some... struggles.
I was able to see more of the weak and dark side of humanity, and by that, my own humanity.
But something interesting happened to me, it was:
At first, Evangelion seemed too complex and too extreme to me... but after getting older and being more mature... I just realized that Evangelion its actually more easy to understand.
I can understand Shinji (an overhated character by the fandom and many otakus)... because he represents the weakness and the scary side to use an Eva.
Same goes to Asuka... she was just a human that suffered as Shinji or Misato did it.
I'm not able to remember everything right now hahaha
Have a good day/night!
