here come the downvotes cuz some people can't handle the truth. I'm entirely sympathetic to Aaron's mental illness because I was raised in a way that gave something similar to me too. Luckily my crash worked out better. Aaron's parents hold him up as a martyr, and I (with no direct knowledge) suspect they might have had a hand in making him behave like a martyr, because I know just what it's like.
By the way, framing this as "good vs evil" and Aaron was good, and he did a good thing, while you don't yourself engage the world the way you are encouraging him to, is the root of the actual evil. The world isn't black and white, it's many shades (and colors) and lighting yourself on fire or encouraging somebody else to is rarely the right way to address problems you see.
