I do think he's trolling, yes, so people probably shouldn't bother arguing with him. Not considering D evil is sorta defensible, but calling Sariel evil is kind of ridiculous. Saying you hold BOTH positions? I don't believe it. Either that or he just straight up has not read the series and is just pulling details from spoilers he heard about with no context. Oh, and as far as Dustin not trying goes, yes he would. He's made it clear that he would kill Potimas if he could and has started numerous wars when he felt it would benefit humanity as a whole. I mean, the moment Shiro gives him a chance, he does cooperate to take him out.
