"Morals" and "goals" are very different things. I might make it a goal to (say) steal an apple from a shop; this would be an example of an immoral goal. Or I might make a goal to (say) give some money to charity; this would be a moral goal. Or I might make a goal to buy a book; this would (usually) be a goal with little if any moral weight one way or another.

Morality cannot be the same as terminal goals, because a terminal goal can also be immoral, and someone can pursue a terminal goal while knowing it's immoral.

AI morals are not a category error; if an AI deliberately kills someone, then that carries the same moral weight as if a person deliberately kills someone.
