Okay, my time was cut a bit short, so the last part is a bit chaotic. However, I do think anyone should be able to work it out for themselves.
The central thesis is:
The only faction that really benefits from any lynch on a non-cultist is the cultist faction. Even a lynch on the austrian/german faction would not be that beneficial for IN and vice versa.

The pivotal mechanic is the inheritance mechanism for the cult recruiter.
When Lock, the Hope of Noblesse, was lynched on day 2, he carried with him a yet unsigned treaty (see story line), indicating that he was in for recruitment, but failed to do so before his death. Without signees, if Lock was the only cultist, the cult should have died with him. Instead, as indicated by Fanderay's CF, it did not die, it is very much alive. So what's happening here; to who has Lock passed the buck and, more importantly, how?
While Lock's treaty was yet to be signed, that does not mean he was the only one starting out as cultist. He could have had a co-conspirator (but why didn't he sign the treaty?), who was either a non-roled cultist acting as heir (possibility A) or a secondary recruiter with a personal copy of the treaty (the absence of signees on Lock's treaty would then only indicate that
Lock did not recruit anyone) (possibility

. Another possibility is an inheritance mechanic that ensures the survival of the cult if the original recruiter failed to recruit someone before his death (possibility C). (Feel free to add your scenario to this list.)
If we're dealing with situation A, then we must ask ourselves if the inheritance is strong (i.e., every time the master dies, an apprentice inherits his powers) or weak (the original heir was the only one capable of inheriting Lock's powers to unite). If it is strong, then going after a non-cultist basically guarantees cult victory: We can weed out only some many, if we lynch the only suspected non-cult killer "so many" means "precisely one", cultists per night, but they keep popping up like wild fire, even if recruitment is only every other night (Lock did not recruit during night one). Every day we "waste" on non-cultists, whether we are IN or german/austians, increases the victory probability of the cult significantly.
If we're dealing with B, the second recruiter possibility, then the scenario for non-cultists is a bit better. While a delay in finding him would mean a larger cult in the long run, as soon as he gets lynched cult size stabilizes and they must fight as a regular faction. However, delay cult hunting for too long and the other factions are guaranteed to get overrun by cultists.
The best case scenario is scenario C, as it's the same as B, but with one cultist less, securing in the long, maybe, another day before cult is victorious.
However, going after anyone outside of the cult faction means increasing the cult to non-cult ratio significantly. The cult gains a 0.5 a member per night, assuming recruiting every other night, the non-cult factions together lose 1.5 members (one lynch, 0.5 is recruiter per night). So, for both the Austians/Germans and the IN, the best thing to do is to go after the cult, culling it and then go after each other. The other way around only ensures a growing cult dominance.
So, as a non-cultist, I do not fear Jalan, he's go another shot at hitting the cult and he would be stupid not pointing his NK there.
