Evil_Dao
I mean, he's cultivating evil qi. But I would say this is a little too far, it risks making his actions heinous rather than hilarious. More humour could help, or a slight walk back. The fact that the soaring crane sect was built up as an overall positive force doesn't help, they just seem desperate and overcome with rage instead of hateable. Rule one of war is dehumanisation.
I absolutely love it, and it could go even darker and I would still love it. It reminds me of Hellsing Ultimate Abridged, one of my top favorite animes even though it's a parody. If you haven't seen it yet, I highly recommend it. This parody is infinitely better than the original anime it's made from.
