That’s unfortunate if an immigrant won’t assimilate responsibly into their host country and causes continuing harm through this policy. You’re just importing future prisoners and criminals.
Refugees/immigrants/etc should be welcomed (I have sponsored refugees in the US), but violent crime must be prevented if someone runs out of chances. You need some recourse when you run out of options and people who have immigrated refuse to act in good faith. Immigration is a gift and a privilege.
I assume you meant integrate instead of assimilate?
I definitely want immigrants to integrate in our society (and am prepared to do this when I travel into another country).
But I would not expect anyone to assimilate - which to my understanding means giving up their previous culture and take on the culture of the host country.
