Intuition to take the place of Torah? Not even Ruach Hakodesh can do that. Hashem directly told Yehoshua that He can’t tell him the Halachos that were forgotten during the Aveilus of Moshe Rabbeinu.
This is definitely an interesting question. We know he will kill but we don’t know when (and we don’t know whom), but he is not doing anything now. In Hashkafic terms we can learn from Ben Sorer Umore that he gets killed, but then again, that’s for Beis Din. On the contrary, maybe that is proof that he is not considered an active Rodef right now. Veyesh Lechaleq.
As to the OQ, I recall reading in Dare To Survive how even when given the chance to kill a Nazi they bribed him rather than kill him. In other words, they payed him for his life. In the Youngest Partisan as well, after capturing a German, Reb Cohen couldn’t bring himself to personally kill him and he left the honor to the others.
