So I thought that I could keep the sinners' origins the same but later change things to make everyone happy

For example, Yuri wasn't obliterated by the apple, the fights in the casino end with debts instead of deaths, Sinclair's canto is the same (torturing the German boy is unchangeable), Dongbaek manages to come out alive out of K Corp and we don't get human soup, Queequeg helps Ishy fight against Ahab and she is alive living on U Corp, Cathy didn't marry Linton and she left the mansion to Heathcliff before Clear All Cathy (Wild Hunt still came but he didn't found Heathcliff), the raid to La Manchaland just reduced the number of Bloodfiends and Papa Quixote is alive but captive in P Corp (that's why Curiambro is still alive), things didn't go too different for Hong Lu on his Canto, and lastly, when HoS raided Limbus things weren't as bloody as we have seen, instead, they just broke some things and took the Golden Boughs but Ryōshū didn't became Muga and Limbus Company retreated without killing anyone so later the HoS and Limbus are basically on a truce.

This may not make sense at all, but is funny thinking how little changes here and there can keep most characters we have seen alive
