Let's clear up some confusion here; we may be arguing about different things:
THIS is a non-sentient summoned 'bone golem' which is the tool of a necromancer. It is dextrous enough to wield a bow (with annoying accuracy) but cannot speak, not that it has anything to communicate, anyway.
THIS is Mortimer Rictusgrin, passed soul who was punished for lies that caused others' deaths by being used to animate a skull that was part of a large pillar of similar skulls in 'hell'; he is sentient, acerbic and witty.
This skeleton again has no individual name, nor any means of interacting or communicating with its world apart from hacking at it with its axes. Presumably animated as part of a mindless horde of minions for the Lord of Terror.
This is Manuel Calavera, departed soul consigned (for unexplained sins or other reasons) to act as a 'Travel Agent' for the recently departed. Ambitious, competitive and sarcastic characterize how he interacts with his world.
...starting to see a pattern here?
Look, I get that some animated piles of bones may be instilled with a sentience or the soul of a previously living entity, but
Animate Dead is a third-level spell, while
Create Undead is a SIXTH-level spell, and even with the latter able to create 'intelligent undead', often said creations are still evil, malicious and violently antagonistic to a near-mindless extent.
So if I see a 'body with no flesh' approaching me at speed, a weapon in its grasp readied for an attack, I'm not going to try sweet-talking this attacker, or attempt to open a dialogue with the intent of gaining understanding between one another, I'm turning it into bonemeal.
...that said, this rule of mine applies
equally to 'fleshy' beings as well, so don't feel singled out.
