The games where abuse is exposed are Japanese novellas with two answers that have little to no impact and three endings where - in two of which someone dies.
It's well written, though. The protagonist gets kidnapped - it's immediately a dark, angsty plot.
But here it's a literal double standard, where for the massacre in the grove you're given an evil Mintara woman to fight for the two of you and build your power.
That's an evil act, consequences? Beautiful drow, because you chose the dark side and defeated the enemy.

And with the only evil man in this game. Something ridiculous is happening.
Consequences... his kisses are rough and the scare of kissing him....

Maybe I think vampirism damns souls and they're going to hell anyway. The game doesn't tell you where the spawns go if you just kill them.
We have a world threat Mind flayer, an ascended vampire are chances to win and it's best to take advantage of every opportunity. The fact that Astarion is euphoric from his triumph - he's not tormented by hunger, he's free to walk in the sun, the vivid senses that had been taken from him hundreds of years ago were now with him again.
There is so much biased information going around about the ritual because Astarion is suddenly now... speaking louder, which he's been saying all three acts and can actually do. M-m, I don't mind.
I never mind taking over a medieval, fantasy city with my secret web of power or just enjoying whatever the world will offer (the former is exhausting)

One of those myths, fakes that have generated insufficient lore about vampirism in the game and what is “ascended vampirism”.
“True vampirism” and dark desires that twist consciousnesses. Dark desires, and twisted minds work on spawns too, because they are consequences of vampirism. Twisted consciousness is a downside of vampirism, undead trait.
It doesn't happen that way, either it works and vampirism twists the mind or it doesn't work - and we need to take the personality apart. (except for the bloodthirsty part, I guess)
Does it even work for “first living vampirism”? The game doesn't say.

Although all he's doing is being Lord in Baldur's Gate and enjoying his reborn senses and his nobility.
Astarion doing what he wants without the yoke of downsides vampirism.
That arrogant Lord, I don't mind, if I was scared of his rudeness and nasty temper traits, I'd choose another companion.
Astarion shows that personality is a complex contradictory thing, not static, capable of different actions.
