Alignment was a poorly conceived mechanic from its inception. Good riddance.
Alignment sucks the nuance out of roleplay. It puts the DM/Publisher in the unfortunate position of being the unilateral arbiter of which solution to the trolly problem is the "good" solution, and which is the "evil" solution. This is anathema to the actual job of a DM/Publisher which is to create a fun and engaging experience for everyone. Characters never have to wonder whether they did the right thing or not. They can just look at their character sheet and see whether they got good or evil points for urging the King to create an open borders policy or adopt a more progressive tax structure.
One arbiter might see Robin Hood as chaotic good because he works outside the law to help people in need. From a more objectivist/libertarian perspective, he would be chaotic evil, because he is essentially just a brigand who uses violence to impose his own ideas of equitable wealth redistribution by stealing the hard-earned, well-deserved wealth of the Dagny Taggarts and Hank Reardons who drive the engines of prosperity. Another might see him as lawful good, fulfilling his duties to the lawful monarch King Richard, in defiance of the unlawful usurper Prince John. Yet another might judge him as lawful evil, fulfilling his lawful duties to the evil tyrant King Richard who led an unprovoked Crusade against the innocent Moors.
A universal mechanic to determine whether Robin Hood should be able to wield the bow of Lawful Good Smiting +3 or not is just arbitrary and silly.
