Here are some ways of a complete monster for the series:

A gem warden in homeworld who likes to kill and abuse the prisoners daily, even if they are in their cell

Maybe even a human, an obsessive human who is willing to do anything just to prove they are right, this means possibly framing the gems through horrible deeds or damaging their moral through the city simply through racism and will attack anyone who disagrees with them

Or like you've said yellow diamond, if she doesn't care about gemlife and will kill loyal gems just because they failed, they disagree with her, or disobey, then yes, however if she is only doing it to preserve their kind then no she can't count.
