The Puppet: had every reason to want Afton dead, and it’s unclear how many casualties she caused.
Black Manta: I don’t know who he is.
Scar: just power-hungry, had no right to do anything he did.
Dabi: Endeavor wasn’t the best father to say the least, and thus he kinda had it coming, but ruining his reputation while he was trying to change feel like karma in the wrong moment.
Erik Killmonger: ok, he had some valid points, but he still sacrificies other Wakandians with no qualms. He’s clearly less sympathetic than his father.
Tirek: from what I recall, he only wanted power. Unless he had a second motive that I didn’t know until now, he had no right in his actions.
About their status, 2 of them are PE, 2 NPEs and 2 VBs.
Conclusion: Charlie gets my vote.
