1. Guns are not human beings, so you're comparing apples and oranges.
2. Banning guns might save one or two lives, but will actually cost more innocent lives, as most criminals won't obey it and honest citizens will have no means of self defense.
Note: I agree with deporting illegal immigrants. I might agree with with making changes to immigration policy to make it easier to immigrate the U.S. (but not open borders, there would still be a "line" and a cursory background check, still would need detention centers to alow time for that check) but what's the point in changing a policy if it's not enforced anyway.
