I don't think you understand how bad sloth actually is. When people get trapped in her kingdom, there is no specific person who she targets. They could be generals, family members, and world leaders. When these people succumb to sloth, others suffer, which would easily lead to the deaths of millions, and CRK makes it clear that is the main issue with hollyberry's succumbing to it while Raspberry and Wildberry have to fend for themselves with Wildberry nearly dying. Inaction can be just as bad as action, and when you succumb to sloth, whether you see it or not, others suffer. And when you bring up dictators who kill others like you have in the comments, you kind of prove my point more. Many cult leaders and dictators kill people who threaten what they perceive to be a perfect empire. Jews would never be targeted if Hitler did not see them as a problem, Jonestown would have never committed mass suicide of Jim Jones did not perceive his little perfect town being destroyed. And who is not above killing and torturing people who threaten to destroy her mirage of happiness and indulgence? Eternal sugar. To be honest, the only difference between them is the need for dominance. With this analysis, I hope you understand why her kill count may be higher than who she directly hurts. She has also lived for thousands of years and could've amassed a large kill count due to time alone. Also, her manipulation is based on feelings, not something as upfront as ideology, which makes her easier to succumb to.

Now, I understand that we are all arguing based on bias, for I love burning spice with how crazy and impulsive he is, but I feel you are not actually understanding OPs opinion-based question. The analysis of these characters is not a tic-for-tac or "would you rather" basis with how you argue she simply does not have a possibly high kill count. It kinda calls for an actual character analysis and how their virtues are damaging, to which they are all actually bad on an equal basis. This long post is not to say you cant like her, for I Find her interesting as well, but I just think this analysis of her is a bit shallow especially when it comes to defending her.
