If you believe the various books on them (which I am not wholly sure I do but I don't find it unlikely) the CIA has always had sites to where it would pick up foreign nationals and move them, and then torture them or do literally whatever.
That's largely what Guantanamo serves as, if I understand correctly.
Historically (once again, if I understand correctly) that usually this was done for "national security" reasons, which I find to be not much of an excuse for destroying people via extra judicial means.
Now the executive is claiming that deporting folks is an issue of that same national security.
Additionally, they are claiming larger powers to do that kind of thing. And it certainly seems that they would like to do it for masses of people, out loud and in public, and ultimately to folks who have been stripped of citizenship in the same way that they have stripped legitimate green card and visa holders of their legitimate right to be in the country.
To answer your question "Or to put it in simpler english can you imprison someone for life by proxy by deporting them":
yes they have always done that (regardless of the legality of that action) and yes it is becoming a more overt attempt to terrify those of us who dissent or who aren't able to conform to their political ideology.
I am not shocked, however- it seemed blatantly wrong for them to rendition people before now. If they can do it to one group, they will likely do it to others, including you and me.
Other than the (predictable) change in scope it's not a new thing, though.
The US public famously doesn't notice when its government commits crimes- the invasion of Iraq being the first large and obvious one in my life. I was shocked then, but at this point I am more surprised that full blown fascism is taking so long to form up. Hopefully I am just being hyperbolic in my reasoning.
