Lust is foolish. Or rather, Lust has a major weakness - she cares about the end results with little regard as to how they get done. Roy is a perfectionist - a strategist with a plan and highly qualified people who will get everything done with their own set of skills. They are literal foils so it drives me absolutely batshit when people claim that Roy meeting Lust is some kind of metaphorical face off of a playboy and his lustiness, especially when only just last chapter we established that the girl on the other end of the line is Riza and the other girls are code names for members of his team.
Roy is acting on love for his team. He has an end goal, but cares about how it gets done. The process matters because end doesn’t justify every means. He’s got plans to run the country but his reasons will slowly unfold over time. He’s got ideas and schemes and back up plans and he is stealthy, quick and even underhanded. Hiccups in the road get taken care of but he never gets rid of something until it’s absolutely necessary.
Lust is acting because she can’t wait for the results. Lust is bloodlust. Jean Havoc was useless to her because he didn’t spill about his work life, and therefore she deemed him to be not too bright. Quite the opposite. Havoc is a genius in his own way, and would never compromise his team or the mission. Lust didn’t care after he became useless to her. She doesn’t care how Envy and Gluttony get the job done, only that they do. They’re at her beck and call, they messed up their job, and now she’s stepping in.
Roy and Lust are opposites. Roy steps in because his help is needed, because he has to protect his team, because he’s invested. Lust steps in because her lackeys failed and she needs people dead already.
I needed to post this because Havoc is a smart, trustworthy guy who knows what he’s doing and Roy and Lust are exact opposites.
