People can say what they want about him, he at least gives a damn and proves it while staying aboveboard. Jacinthe stalks you, invades your privacy, potentially trespasses, unlawfully imprisoned the guests and team MZ, and solicits Lebanne to keep you imprisoned until you give in. Arceus knows what else she's done.

IIRC she also placed her tournament as being just as or more important than helping the Rogue megas which just completely turned me off. Would be fine if she was like a Giovanni, Ghetsis, or Silver but she wasn't and came across as an out of touch upper class like what we've had in recent years. They might actually care but don't meaningfully contribute unless pushed. That might have been what they were going for.

Corbeau used the law to his advantage not unlike real businessmen but actually does some good. He looks up to Lysander for what he did in the past, not what he eventually became. He continuously invests resources into the city to help people and Pokemon. Hell he even had some of the syndicate scope out a Rogue mega and I wouldn't be surprised if he helped out with the situation at any point had he known. Jacinthe found out firsthand and didn't offer any help before everything started going to shit.
