It seems fine however death usually forces the noble phantasm into a sort of deactivation unless it's a curse. Likewise characters with some sort of skill like say bravery should be able to resist it.

I do have my reservations as it could end up crippling some servants however the masters, or servants in question should be able to go through some sort of luck check to resist the thing. Also the people in question would have needed to do something deplorable in life for it to even work.

I guess we can treat it as being a curse then, though I'd be okay with removing that part if the noble phantasm's effects staying even after the servant's death is deemed too powerful. On Bravery, yeah I thought so too. Basically, any skill that grants a strong constitution would theoretically make it easier to resist this noble phantasm (depending on its rank probably).

Luck check sounds fine too. And yes, it's meant to be more effective against evil people. I considered making it work against people who have commited murder, but since most heroes have killed at least once, that would've probably been too much. I think that basing this off the target's alignment would be the easiest way to go about this, imo (e.g. Chaotic Evil characters getting hurt by it the most, Lawful Good characters being able to resist it for the most part).

I'm also fine with all the above being judged in a case-by-case basis.
