Tyrant Queen massacres family for ideal heir! Crusader Kings 3

Crusader Kings 3 playthrough, following the successful campaign from the ck2 game, I embark on a different type of journey in ck3. The aim in this campaign is to reform a religion as fast as possible, enable indulgences, criminalize as many traits as possible, and profit! The money will fuel all other endeavors and I will have the added bonus of being a religious head, so I never have to worry about faith elements blocking me. The ultimate goal would be to resist a crusade from the Pope and riposte with my own Holy War and take over Europe and the rest of the world!
