Why does Aneeka's Pakistani cousin tell her he does not want to know her plans?

Aneeka's Pakistani cousin tell her he does not want to know her plans because Aneeka has more privileges as a British citizen than he and his family have living in Pakistan. Her cousin tells her that they spend their whole lives making sure they do not do anything that could get a visa application rejected, Parvaiz decides from his privileged place to join ISIS, the British government expects Pakistan to deal with everything rather than taking care of Parvaiz's body, and that Aneeka now comes in for some "stunt." He says he does not want his family to have anything to do with her plans.
