[Hermann the Cherusker]

St. Andrew Bobola was hated for reconverting individuals who had left the Faith and become orthodox. For that he was a marked man and eventually martyred.

I would say left the Church, not left the faith. In any case, the level of hatred poured out after 1596 in Russia was a direct result of Roman bad faith actions towards the easterners who had remained faithful (as in Calabria and Sicily, where the Churches were forcefully Latinized), and the suspicion spread about in Russia that the Unia was a Polish plot to subvert Russia.

It's still the case that St. Andrew Bobola, that great Polish Jesuit hero, was a marked man for reconverting individuals from orthodox to Catholicism. nit picking how they got there, doesn't change the fact that he eventually was martyred for convincing people to be Catholic again. To my mind, that means the orthodox are not Catholic. Call it what you want.
