I agree that by definition, Arima was an antagonist in the original series. (So, too, was Amon for much of the series.)

In :Re, things are obviously more complicated now. We honestly don't know what Arima is thinking, what his original motives were, and whether things have changed since then. As such, it really is hard to judge him accurately. He's still far too much of a mystery.

However, I do think even with his memories, Kaneki/Sasaki would have very conflicted feelings about him. Arima has been a father figure to him for the last nearly three years, something that Kaneki lacked for much of his life. Ishida hasn't told us much about Arima the Person, but what little we do know shows that he's a very lonely and isolated person. If we go by the choice of "A Crossbreed", it's likely that Arima does have some genuine affection for Sasaki.

I think, in the long term, the relationship between them is going to be a major source of drama and tension.
