[General]
-- I'm not a fan of this difficulty spread. Despite Hate being 3 stars, it plays like an upper-level normal and you really need an easier difficulty.

00:59:442 (5,6,7) - This pattern is incredibly difficult to read properly. The spacing is misleading (it appears that they are all the same distance from each other in of beat placement on the timeline). Besides, moving (7) back one tick works better anyways. For the record, you did as I suggested at 03:39:004 (4) so that should give you even more incentive to fix this.
01:02:817 (1) - The 1/2-beat repeat slider does not fit very well for this part specifically. It's awkward when playing. A 1-beat slider (starting at 01:02:817 and ending at 01:03:192) would fit the vocal line and play much better.
02:16:317 (1) - I'd recommend removing this slider-velocity change for two reasons: 1.) it's inconsistent with what you did last time when it was spinner -> pattern -> spinner pattern; 2.) it's very easy to mistake as a 1/2-beat slider because the player has no hint of a slow down. Do as you wish but I think removing the SV change and making it a normal 1-beat slider would be better .
03:29:817 (2) - You need to add a new combo here so the spinner ends properly. Same with 03:35:817 (2), 03:41:817 (2), and 03:47:817 (2).

00:13:129 (2,3) - For the sake of the overall difficulty in this map, it'd be more intuitive to the player if you added a repeat at (2) and removed (3) at first so they know what is coming.
00:15:004 (1) - This new combo spam is not doing any justice -- it's just making the HP drain faster. Combos signify a change/transition in the music. These do not make sense. Remove it. Do the same at 00:18:004 (1), 00:21:004 (1), 00:51:004 (1,2), 01:52:504 (1),
00:22:692 (6) - A slider's end is not a way you want to transition into a new stanza. Ending sliders on downbeats is incorrect beat placement and does you no good because it doesn't stress the beat and it messes up your combo patterns. Also, you haven't done anything like this until now so you're starting a measure and ending a new measure inconsistently. Shorten it to a 1/2-beat slider, add a hit circle at 00:23:067 (7), and add a new combo on the newly placed note. Don't forget to remove the combo at 00:23:254. (There are also more ways you can fix this; be creative.)
01:51:192 (4) - ^
02:00:192 (6) - ^
02:57:379 (4,1) - These few notes don't follow the vocal line very well. You're ending sliders where beats should start. Replace (4) with a hit-circle, add a 1-beat slider at 02:57:567 (5) (and a new combo), remove 02:57:942 (1), and add a repeat to the new slider. On time timeline, it should look something like this:

03:13:317 (5,6) - Leaving a gap between (5) and (6) calls for an awkward transition. Make (5) into a 1/2-beat slider.
03:21:192 (5) - Just like before, ending sliders on a downbeat like this does no good. Make this slider into a 1/2-beat slider, add a 1-beat slider at 03:21:567 (and a new combo), remove 03:21:942 (1), and add a repeat to the new slider.
Timeline Reference
03:22:692 (4) - Same thing. Make this into a 1/2-beat slider and add a hit circle at 03:23:067 (5) (and a new combo). Make sure to remove the combo at 03:23:442 (1).
03:42:192 (4) - You know the drill. Make sure the slider doesn't end on the downbeat anymore.
01:02:442 (2) - Just like in the other difficulty, you need to add a new combo here manually so that the slider ends properly. Same with 01:08:442 (2).
[Hate]
01:08:817 (2) - Add a new combo here so that the slider ends properly.
01:21:567 (5,1) - Remove the combo at 01:22:317 (1) and add it at (5). Combos, as mentioned above, signify a change in music. It makes more sense this way.
02:35:067 (1) - Replace this whistle with a finish for the sake of consistency.

-- Centering the difficulties in an oni at this level is pretty lame. Consider increasing the OD and HP drain by 1 so it isn't an easy SS/.
Yeah, like I said before, you definitely need an easier difficulty. [Hate] is well constructed and you need not do butcher it to make it easier. If you want me to recheck it, make the changes and respond with what you did and didn't do so I know where to start. PM me when you think you are ready.
