Can pronoun "it" be used instead of (personal) pronouns "her" or "him" in a disparaging/derogative manner especially in the personal pronouns?

I've watched a movie wherein a dead body was found and, without saying anything, they've been told just to "burn it!". I know this could have been strictly referring to "a body" — a neutral noun. However, the "burn it!" was said in a really disparaging manner.

And let's suppose that the man who said it knew the man who was killed. Still, can we use "it" instead of "her" or "him" in that manner emphasising the hate and scorn towards a particular person?
