I lean Dimentio since Bill has friends and was implied to have some guilt about destroying his own dimension. Dimentio was going to destroy the multiverse. If you absolutely had to pick which one would you choose?
If you are going to add disqualifying categories to Rejected Evil pages please give a reason why just because a villain is not Pure Evil doesn't mean they are suddenly Affably Evil. This is your first warning if you do it again I will contact an admin to block you
On some of these pages, I've notice you are adding categories that do not qualify like on the Im page and others. Do not continue to adding categories onto Im's page or other pages when we do not know much about them. This along with the 'type of villains' thing too. That information is inaccurate.
Do not make a re-proposal with out both authorization and approval as so far you do not have permissions. Also you seemed to miss the big reason Lord Shen was voted down: he cared for the Soothsayer and even lets her go despite there being no reason to keep her alive. He had no issue with killing his enemies and by the end had no use for her yet just let her walk away free despite her antagonizing him.
Stop adding genocidal on Akainu's page. I already explained in the edit summary how he cannot qualify for genocidal. He is targeting pirates not a race of people or species. You have not given a reason for adding this onto the page. And, your attempts of forcing this onto the page with no reason is seen as counter-productive editing. If you continue to add this, I'll report you to an admin.
