What's the point with that quite lackluster story in Endwalker?

[Tama-Kanzashi]

For a character to be a villain their actions need to be motivated by evil intentions which Venat lacks.

Of course she is evil. You can't look at a character killing a whole race of people and then say "oh that wasn't evil because she meant well". No matter how much media likes to push the approach of "the end justifies the means", no, it doesn't. It absolutely doesn't.

Otherwise that guy pushing the button in The Dead Ends to kill everyone on his planet also isn't evil because he meant well and ended the war. Sure he meant well, but it's still evil. And unlike Hydaelyn he still has his "I...killed everyone..." moment. How mysterious.

And even if you think murder isn't evil enough, she is pretty darn evil on a personal scale too. Sure, the WoL has devolved into a pretty mindless muppet at this point, but it's important to point out that we only got to that point because she manipulated, lied and tampered with them from the very start. But if that still isn't evil enough, how about deleting every trace of her own people's culture from the face of the planet? Every memory of them? Making a flesh puppet (forum alt, hydaelyn taught me to use one) to talk through by killing a girl and then discarding her once she is done? How about not being interested in all the shards and what happens to them unless provoked into action?
How about her own servants on the moon? The Watcher doesn't have memories of his past life as she intentionally didn't give him any, basically being a glorified familiar. And the loporrits, even if they are annoying as heck, never got any communication from her for 12k years while she was apparently able to talk to Sharlayan. Didn't even send them a message. I guess it was funnier to watch their rabbit hearts explode when they realized they built everything wrong.

But I guess that's all benevolent gentleness. After all she speaks with a soft and calm voice.
