Because cultural differences have pushed him to crimes.
For example. I'm Spanish. My neighbors are Moroccan. The father didn't once in his life acknowledge my mother. He wouldn't talk to her. He would ignore her if she talked. To him, my mother was barely a person because she was a woman. Now this is extreme, but legal behavior, if it ever came to pass that he crossed some lines he might have gotten deported.
His son though? Stealing, selling drugs and beating his sisters are some of the things he has done, but he is a Spanish citizen, just like any other, so there is no magic "back to your country" card to play.
My point is that it's legitimate to pick and choose who you let into a country because the consequences of doing so are far-reaching. Because even if you might be able to deal swiftly with the guy you let in, every human being takes culture with him, and culture spreads. Integration is the most important phase of immigration, along with making sure those people you let in aren't going to be pushed into a life of crime and I don't think anyone ignoring that is taking immigration seriously.
