D&D never really tried to sell "animating the dead is evil" as a moral principle - they just stated it. By Heroes of Horror, I think they just gave up, admitting that a focused necromancer can be perfectly good otherwise, but their powers are still evil because shut up, and their familiar summoning was still linked to the Lower Planes because they got warlocks and necromancers mixed up again.
Speaking of undead, Crucible of God from the Gehenna book for VTM doesn't even try to be subtle about its denial of player agency.
The game tells the ST to railroad the PCs for maximum fuck-you from start to finish, and forces them into a theological deus ex machina at the end if they don't want Tzimisce to eat the entire world.
That is when the players have their PCs pull off their skin masks and reveal that they have been faithful slaves to Tzimisce all along and will do their part to make it's will be done.
