What makes little sense, then, is that under the assumption that you are one of the bad guys in league with mindflayers (except he just saw you killing other intellect devourers, by his own admission, but ok...) it would be a clever idea LURE US into making a kind gesture for him.
I don't think he really saw us killing intellect devourers, I think he might say this to flatter our Tav. I think he pretends to be some helpless noble, who can't defend himself, and our mighty Tav has to save him. So to me, luring us into making a kind gesture for him is exactly what he does.
As a player, I must admit I like the emotional rollercoaster my poor Tavs (generally kind and helpful) must be on, between being angry at him for his selfish/arrogant and sometimes spiteful behaviour, feeling sorry for him when they learn about Cazador, and being charmed by him.
I always have him join the party, because I really want to know where this is going. It is strongly implied that he was not even a nice guy before he became a vampire spawn, but I wonder if we can have a bit of a positive influence on him. I'm always up for character development.
