I cheesed the demon of hatred but honestly wasn't even fun to fight. Game got easier when a user here suggested not to worry and suddenly i breezed through all the content.
Going into each fight with the mindset of doing it for practice made everything easier for some reason.
Sekiro and Elden Ring were developed in parallel. At least to some extent. That's why Elden Ring has next to no influence from Sekiro. Some people say Sekiro inspired Elden Ring's posture mechanics but I think that is a bit of a stretch.
