Can someone explain to me why Cardinal Richelieu is a bad guy aside from the thing he did the previous life?

From his pov, we saw what he saw in the Vatican--men of supposed utter devotion to their god are instead devoted to gaining and maintaining power and wealth and perhaps even lust. Richelieu truly believes that he was chosen by god to continue his life for a reason, maybe to make a difference in the world idk. He wants to get rid of the corruption in the church, but as a newbie he knows he's powerless so he bides his time, gaining influence, until he can strike confidently.

But was Meissner right about him? Is Richelieu not doing it for the noble cause of purging corruption, but is actually just doing it to be on top? Does he just want power?

Lowkey would rather have him not have that kind of twist to his motivation. I think it'd be interesting to see the different choices he will make in the second life, where Shuri just unknowingly helped him oust a corrupt priest and bring to light the many crimes he committed while under the protection of the church. Cuz in the first life, he alone was the brains of his operation, and it seemed that everything all fell according to plan, meaning no one was acting out of his expectations. Shuri, in this life, is acting a bit different from what he expected. It could be a chance for him to tweak the details in his plan to not involve her brutal death? Maybe he'll find that there's another way to purge the corruption in the country aside from a whole ass war? Maybe he'll finally get enough sleep to reduce those eyebags?

Idk man my brain is too small for scheming
