Except even the fact that he likes killing people literally makes no sense given that he has been sitting on his arse for the past 400 years doing fuck all. And, suddenly, he goes crazy in F. Rogue's timeline and proves that he can easily take over the world...

It was so goddamn obvious that Acno had a hidden agenda, if for nothing else then at least to get the power to rule over the world. Except Mashima apparently doesn't think so. I'd like to say he had to cut it out due to time restrictions but I'd just be kidding myself. He just doesn't have a single idea what he's doing.
