Good lawyers will excuse jurors based on how they will likely relate to the case being presented. For instance, here in Brazil, most defense lawyers will excuse jurors of Japanese origin based on the idea they would impose tougher moral standards than other groups.
Lawyers are obliged to always offer the best possible defense to the extent of their abilities, and that includes selecting a biased jury if that's possible.
