It depends of it's hardness I'd guess skin is not leather (in any terms).
If it is a scaled humanoid skin then maybe (if putting in thickness / hardness factors) it could count as thin light scale armor, but still not leather - otherwise I'd guess it would count originally as clothing made from skin - you could enchant it with magic I'd assume and then make up a good back story how it is made of a fallen angel skin that the son of a devil was tough to put down and took enormous effort of all the heroes etc which would make it 'non-evil' I guess?
Clothing isn't evil based on whatever it is made of.
If you curse it+enchant or just decide it is evil and act like it is evil when ever you encounter it is can then probably be evil _to you_, probably some it doesn't matter at all, some might consider it a bit 'not in the style', some repulsive etc.
Skin suit - add fancy additional descriptive names after it.
If you magically enchant it provide same armor factors than some other armor it is magical.
Hope these thoughts gave some insight bonus to your question.
Cheers,

Would such armor have an different stats than regular leather armor? Also is just wearing it evil (even if you didn't kill the "donor").
No and no. The origin is just flavor text, unless you're making armor based on the human spirit (sort of like magical troll hide armor might let you regenerate). Cow skin leather is not any different than ox skin leather in the game rules.
It isn't evil to wear it, but it's certainly evil to make it. In the Warhammer setting, dark elves are always wearing kheitans (leather armor) made from human or sometimes dwarven hide. It's just casually mentioned to remind you what they do with their slaves. In A Song of Ice and Fire, we learned that making human leather boots is horrible ... because they don't last.

I can't believe I'm going to talk about this, but sure why not?
Human skin was used to create several light leather products. Examples are parchment, book covers, gloves and other 'streaching' leather garments. Human leather is very thin. Human leather was occasionally used to create thin opaque sections of leather for use as windows. Human leather is comparable to Pigskin but of a generally lower quality.
All in all its not something you'd use to create armor. Even as just straps it would be too weak. If it was included in armor, it would be done for decorative purposes, not functional. Considering the circumstances, I believe the craftsmen would use recognizably human parts such as the face to emphasize that it is human skin rather than trying to disguise the fact.
