SCP-2747
I am mostly going from profiles
Caroline and Irotsuki are probably the top 2 I don't know about them.
3rd we have the narcissist Monarch of pointland who literally can't comprehend anything other than him self.
4th Snakebite he is a murderer.
5th only here to fill the last spot SCP-2747 used the Scarlet king as a tool to destroy all of existence(failed) and the scarlet king is effective the embodiment of evil with scp-231 being his most famous crime. And SCP-2747 likely used similar beings to the scarlet king countless times.
