Glory to Marik
Do they? I always read the batman arguments about the actions, not about whether he has a sunny disposition or is surly or whatever.Say what? Alignment as personality type is a big part of how alignment operates in the popular consciousness. When people debate a fictional character's alignment, it's done with the same manner and purpose as when people debate a fictional character's Myers-Brigg's personality type. You say that it has never been that but it is often linked to personality and personal dispositions in the 5e PHB, and I would say that it is treated more so as an aspect of personality than it is to the factions that a character aligns themselves to.
Just looked at 5E CRB. "A typical creature in the game world has an alignment, which broadly describes its moral and personal attitudes. Alignment is a combination of two factors: one identifies morality (good, evil, or neutral), and the other describes attitudes toward society and order (lawful, chaotic, or neutral). " That doesn't sound like personality to me. I could see it guiding personality, but its not like being Lawful Good means the character must be smug, happy, or particularly tenacious.
