Nobody "deserves" to stay in another country unless they are there legally.
It's odd to me that people started worrying about ICE en mass when Trump became president. It's an organization that has existed since 2003. In addition nearly every country in the world has similar or more stringent policies. Yet no one talks about that and they act as if ICE is unique in some capacity. It's hard to see that as anything other than politically motivated or misguided by media propaganda.
It would be unsustainable to let in everybody who wants to move to another country. That's why quotas, background checks, etc exist.
Entering a country illegally knowing that it will mean you'll be splitting your family in half speaks volumes about the morals and compassion of the person who does that.
