I came up with another proposal, now I don't know about this one since they have too much corrupting factors, but they subverted them by the end of the fourth movie.
What's The Work?
Lethal Weapon is an American buddy cop action-comedy media franchise.
Who Are They?
Martin Riggs is a police officer for the LAPD and is reckless and suicidal. Roger Murtaugh is also a police officer for the LAPD and is much calmer and more cautious.
What Makes Them Close To Being Pure Good?
They stopped General McAllister and Jack Joshua's plan to sell heroin and saved Rianne from McAllister.
They saved countless lives from danger multiple times.
They protect Leo Getz from harm from the South Africans and save him when he was captured by them, even if he was annoying to them.
They stopped Arjen Rudd and Pieter Vorstedt's plan to smuggle illegal shipments of gold krugerrands.
They stopped Jack Travis' plan to sell dangerous weapons and his arms dealership.
They stopped Wah Sing Ku's plan to get the Four Fathers out of prison and buying their freedom with counterfeit money.
Although they didn't like each other at first, they still worked together and form a friendship by the end of the first movie.
Martin Riggs
Although Riggs was suicidal and anti-heroic at first, he started to subvert those qualities over the course of the films and eventually by the fourth film and becomes more heroic and friendly after being part of a family.
Also, Riggs was very mischievous as he constantly tormented Leo Getz, but he subverted this by the end of the fourth film after hearing his backstory and realizing how much of a good friend he is and admits he was terrible to him.
He loves his deceased wife Victoria Lynn and usually visits her grave to give his love to her.
He cares about his best friend and partner Roger.
He tried to save Leo from the assassin that tried to kill him.
He protected his former girlfriend Rika Van Den Haas from the South African diplomats.
When he realized Pieter Vorstedt killed his wife and his former girlfriend Rika, he avenged them both by killing Vorstedt.
When Roger accidentally fires his gun, Riggs takes the fall by pretending to be angry by throwing a tantrum and hitting the lockers to prevent Roger from getting in trouble, saving him.
When he went to where Roger was at the docks, he tried to talk him out of depression and become a cop again.
Although he had a rocky upstart with Lorna Cole, (his new girlfriend and later wife), he came to her aid when she got shot by Jack Travis and tried to revive her.
Roger Murtaugh
He is protective of Riggs and cared about his problems.
He is much more cautious and less crazy and anti-heroic than Riggs was at the start.
He confronts Riggs over his suicidal tendencies.
He often acts as the voice of reason to Riggs and tries to tell him the consequences to his crazy actions.
He is protective of his children and cares deeply about them as he threatened Riggs not to come near Rianne.
He kills Arjen Rudd, ending his reign of terror.
Although he killed his son Nick's best friend, Darryl Smitthers, he truly did not know he was Nick's best friend and went into depression over it.
Although he was as mischievous along with Riggs towards Leo, he subverted this in the end of the fourth film.
What Prevents Them From Being Pure Good?
They are both fairly lethal as they have killed many villains, although they still stopped them.
They are both a bit reckless (mostly Riggs) as well and sometimes cause destruction in the city, though this is accidental most of the time.
Final Verdict
Yes
