Also is acnologia really that bad? A Dragon Slayer who slayed countless dragon. We also don't know what pushed him over the edge(dont read manga) i mean for all we know dragons couldve slaughtered his family Or the only way to save mankind from zeref was to bathe in dragon blood so he could be strong enough to face him
