these are very complex issues; I think it useful to state that the Chazon Ish zt’l says that “rasha” as termed by Chazal no longer exists in our experience. what we see today by most Yidden is tinuk shenishba.
though I have not discussed this with any Adam Gadol (yet), I would propose that someone who is pushed away from Yiddishkeit, through legitimate circumstances (not just looking for an excuse, classic bechirah) is also bichlal tinuk shenishba in the sense that that person has been forcibly removed from authentic Yiddishkeit.
No less than Moshe Rabbeinu himself is criticized for saying “shimu na hamorim” by the be’er & “rav lachem bnei Levi” by Korach–even though he was 100% correct in his assertions.
Be very careful how you judge, describe, feel or whatever lashon you want to use, the neshoma of another Jew.
Take to heart the words of Hillel-“al tadin es chavercha ad shtagiah limkomo.”
