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.

I just kept playing through the game until NG+4 then got a semi-decent farming route through the bridge with the elite government agents with fire weapons that yeah still took an hour or two.
