I understand disliking Lae'zel for her actions and words in Act 1, at least. Kind of. But she's just a githyanki trying to do her best for her kin and her leader. I also like how she and Shadowheart bicker in the beginning of the story. And it's not like she is evil, skeezy, or bad-mannered. Now, Cazador and Gortash on the other hand...
Laezel is evil, though, as most githyanki are. They are a supremacist, xenophobic race, which view others as their lesser, and whose society is sustained by raiding other worlds. The Lathander monastery is an example of that; the githyanki have invaded the place, murdered all the monks and people looking for healing, in order to establish their creche. If you are familiar with githyanki, there is little reason to trust Laezel in the beginning of the game. Because even if her people had a cure, it is very unlikely they would offer it to an outsider.
