Being relatable and having depth are two different things. Being relatable is a matter of the audience understanding the situation through their own experiences and comparisons. Having depth is a consistency formed through good writing establishing a character through multiple scenarios. I’d hardly say the devils and demons are poor characters in D&D; they’re alignment- locked and thus extremely unrelatable- and this doesn’t extend as a result of the alignment system either. The devil of many fables is unchangeably evil, as the true fae are simply with orange and blue morality. Even on a more human scale with characters like that of serial killers (who can be simply born wrong) people find them interesting as characters due to their consistent characterization.
