Alighnments don't tell squat either. Lawful Neutral? Judge Dredd or Mike Ehrmantraut? Chaotic Good? Batman or Dirty Harry (though I'd argue he isn't good like at all, but anyway)? Lawful Evil? Anton Chigurh or Dick Chaney?
Even on the easiest axis on the grid, Law-Chaos is vague at best. What is Law (baby don't hurt me)? What kind of law does a Lawful character cherish? Lawful may be a by-the-book cop and it may be a mafioso who honors omertha.
Then, what is Chaos? What kind of law does a Chaotic character resent?
And what is Good and what is Evil? Philosophers have broken countless spears about this question since the dawn of time and none managed to get a workable answer.
Alignment chart could work in a game about an ancient order with strict dogma that wages war against evil daemons. Support Dogma? Lawful. Are willing to bend it? Neutral. Oppose it, as it's too rigid? Chaotic. Working against daemons? Good. Don't care? Neutral. Serving daemons? Evil.
As it is, alignment system in 3.5e or 5e needs so much clarifications to actually work that alignment doesn't add anything to a description anyway.
A lawful guy lives by a code and generally respects discipline, family, honour and tradition.
Examples include Frank Castle, Superman, Eddard Stark, Mando, Stan Smith, Lucius Vorenus, Sturm and Steel Brightblade, Mike Ermantrout, Judge Dredd.
A chaotic guy rejects those things and is impulsive, reckless and unpredictable.
Examples include Rick Sanchez, Anakin Skywalker, Jack Sparrow, Deadpool, Roger the Alien, Titus Pullo, Bronn of the Blackwater.
A good guy rejects violence unless in self defence or the defence of others and avoids harming others. They're altruistic, merciful, kind and self sacrificing.
Examples include Superman, Iron Man, Anakin Skywalker (pre fall), Eddard Stark, Caramon Majere, Vision, Captain America, Jon Snow.
An evil person is prepared to harm others for their own ends, or actively embraces harming others for the same, or simply lacks empathy for the pain and suffering they cause.
Examples include Darth Vader, Frank Castle, Titus Pullo, Rick Sanchez, Raistlin Majere (black robes), Roose Bolton, Tony Soprano, Dexter, Mike Ermantrout (by Breaking Bad).
Its really not hard to figure out.
