What alignment would you associate with each class

[Unoriginal]

Hey

I know you can mostly be any alignment.
If your going based solely on the class descriptions of the class including subclasses like Monster Ranger, Abjuration wizard, Assassin, etc what alignment would you give them?

Classes don't have alignments. People have alignments, and some people have classes.

At best you can say that Paladin orders attract lawful people, because it is hard to keep an oath between you and the universe without having the behavior indicating a lawful alignment. The Oaths of Devotion and Redemption tends to attract good people, and the Oath of Conquest evil ones, for the same reasons: hard to follow the tennets without having the behavior indicating the alignment in question.

Oathbreaker Paladins are going to be near universally evil because you can't be this subclass unless you've broken your Oath (not inherently evil by itself), reached the bottom of the morality barrel, and then kept digging while refusing any chance of not being horrible. And even if an Oathbreaker wasn't evil, all Oathbreakers become Death Knights once they die, so deliberately refusing any chance to not end up a powerful undead who torments the living is pretty skeevy in itself.
