Stuff like Code geass and FMAB were really inspirational to me because how they were about rebellin against an overpowering foe, pain, hardship, sacrifice. Even naruto and one piece had moments of them. Dunno if that's what you meant but there's that.
Also shows like Ajin and Shinsekai yori among others can make you hate human beings by reminding you how cruel most of us can be.
Also anime romanticized boxing for me as a sport with rainbow nisha rokubo no shinchin , megalo box and even hajime no ippo.
