The person who trespassed ruined their family's life when they chose to create a family in an illegal situation or involve their family with their illegal act. The government of the country that was trespassed upon is not the one ruining lives. That's the major point.
Your second paragraph is a variation of the same point I answered above, disregarding the fact that I would safely say I live a majority of my days without breaking the law. But if I do break the law I am doing it understanding the consequence. Can you document for me why someone who actually is breaking the law daily isn't willing to do the same?
Your edit is actually more absurd. It is not a human right to be allowed into the United States. I think I'll have to bow out at this one.
Its the very ideal upon which we build our modern national myth.
