I read in vinaya, sometimes the Buddha said if someone killed an arahant, raped bhikkhuni, or did many other actions (I don't remember exactly), then he said, if that one hasn't ordained, then isn't allowed to ordain, if that one is ordained, then is expelled. IIRC, there were cases when people killed arahant, raped bhikkhuni before ordination, then the Buddha didn't allow ordain them.
Are those actions equal to parajika? I.e, even if they somehow can get the ordination, if others find out their actions, would they be expelled?
