Imagine Skyrim or any big RPG where you can't enter NPC houses, the whole "morality" angle of it is silly. This isnt real life.
Equally silly things:

"Oh, we can't be a thief, its a villain job" - Yoshi-P. Sooooooo.. former Final Fantasies are bad with their thief main characters, and now we got Reaper and Dark Knight lol.

"Oh, it would be silly to have a black mage running around in paladin gear" meanwhile they give us plate glam for all jobs, and silly glam like animal suits and modern clothing. But won't let us mix glam up crossjobs.
