This is why it's too bad to hear Astarion is so obviously evil.
that is an opinion that is not shared by everyone. if you dig deeper into astarion there is a justification for a lot of his behavior. a lot of people confuse self-serving with evil, but as i said, once you dig deep enough, you understand all the motivations behind a lot of what he does or says, & he is by far the best romance option & the only one that even acts like a romance even happened after the fact. with the right options, there are chances to read his mind, dig much deeper, see how truly damaged, regretful & pained & just plain sad he really is, & to have him open up to you about the horrific things he has been through, had to do, or had done to him. he has many, many, many layers & definitely puts up a wall & acts a certain way to hide what is behind it all... & of course, he is hands down, the funniest character, with the best dialogue & an amazing voice, which easily makes him the most interesting companion & the one i sympathise/empathise with the most... so there's that lol (in other words, not everyone believes he is the most evil, & again, there's a difference between being evil & being more interested in your own freedom & survival than any other concerns).
