The last character you really hated

[Jade Harley]

If you don't hate a villain for the things they've done, they are NOT a good villain.

Interesting point, though a debatable one.
How do you account for different people hating different things? For example, I loved Nealapph, I thought he was a fantastic character... I was actually really surprised to see Aaron say he hated him (though it does explain the change to Tearen).
But based on what you said, that should mean that in my opinion, Nealapph was a bad villain, which isn't true at all.

Lol you misread everything I said so much. Honestly, it's kind of unbelievable that anyone wouldn't hate the things Nealaphh did. The character was fantastic, and if you had read the my response to Tearen maybe you would've caught onto that. But, it basically annihilated entire planets in its home universe. Terrorized various secondaries throughout its OV career (see Tea's threads in the Vasty Deep, it is TERRIFYING how totally creepy and disgusting and unsettling that thing's treatment of secondaries was.) Experimented on secondaries.

That, in my opinion, makes him a good villain. If you don't hate a character for killing, tormenting and experimenting on other people with zero remorse or human emotion, that's on you. I personally found this character to be horrifying, the antithesis of humanity, and thus I hated it.
