TheThe spell says the animated undead are "a foul mimicry of life", implying their decisions in life have no more effect on them mentally. Also, when a creature retains its alignment and personality after being targeted by a shapeshifting feature/spell, it explicitly says so, for example Polymorph says "It retains its alignment and personality." The spell also says "The target becomes a skeleton if you chose bones or a zombie if you chose a corpse (the GM has the creature’s game statistics)", meaning the zombies/skeletons you make are no different from a random one you might encounter, except for appearance.
Also, when a creature retains its alignment and personality after being targeted by a shapeshifting feature/spell, it explicitly says so, for example, Polymorph says "It retains its alignment and personality." Additionally, given a zombie's INT score of 3, and Neutral Evil alignment, it is unlikely to remember who you are and help you even if it wasn't a separate creature. Finally, zombies can still be targeted by True Resurrection, as stated in the MM: "Once turned into a zombie, a creature can't be restored to life except by powerful magic, such as a resurrection spell. (Raise Dead and Revivify cannot do this though)"; this implies that zombies are a distinct entity from their original person.
