Even calling god a "cosmic abuser" might be being far too nice to it. That title doesn't even begin to reflect the infinite amount of suffering it causes.
Even the most awful and terrible person (like breediots) you could possibly imagine would still have infinitely more worth and means to be redeemed than this so called "god." There is not a punishment imaginable that you could give this entity that would be enough to right the wrongs it has done.
There is not an insult disrespectful enough in any language ever made that is as disrespectful as it deserves to be called. This god doesn't even deserve to be called a "He" or even "They" since that would be implying there is more to it than just a pathetically repulsive and cold empty framework of malice.
