It's not that I find him evil, in fact I don't find any of the companions evil, no matter their disapprovals. I always strive to making the camp as friendly and acceptable as I possibly can to all companions, I even let him suck my blood.
My opinion of him is that he is terribly inconsistent, but clearly a tortured soul. From being overly confident, to deeply reserved, to flirtatious and then outright murderous if you say the wrong thing. I fully understand every companion except Astarion, because he is all over the place with his feelings, so I can't pin-point yet the true Astarion. But I'm sure he will become very enjoyable once I get to know him better when the game releases.
you do have love with Astarion. or you will not let him touch your neck, will you?
"man are not bad, woman do not love"
though I am a good man
or at least not a bad man.
