Legend
Mike Ermantrout and Frank Castle are LE because they live by a code, respect honor, family and tradition, but are prepared to engage in pitiless murder, torture and harming others.
Darth Vader and Rick Sanchez are CE because they're reckless, unpredictable, have no code, and engage in murder, torture and harming others (including actual genocide).
Superman and Jon Snow are LG because they believe in family, honour and tradition, are altruistic and merciful, prepared to self sacrifice and they reject harming others unless it's in self defence or the defence of others.
Anakin Skywalker (pre fall) and Jessica Jones are CG because they are reckless, impulsive and unpredictable, but also altruistic and self sacrificing and avoid harming others unless in self defence or the defence of others.
Judge Dredd and Lucius Vorenus are LN because they believe in a strict code, and respect honor and tradition, but do not repudiate harming others, nor are committed to altruism.
Deadpool and Jack Sparrow are CN because they're unpredictable and reckless and untrustworthy. They lack the conviction to avoid harming others, but lack the altruism to make them good people.
For alignment changes in fiction look at Vader (CG to CE) Arya Stark (CG to NE), and Raistlin Majere (CN to CE).
Are we really still confused on this point?
