I failed to mention this note which seems to indicate that an Overseer was overcome by the call of the bonecharms themselves and stole one to 'protect' it from his brothers, perishing in his attempt.

This combined with the other evidence strongly suggests that bonecharms in general have corrupting/damaging properties similar to that of runes.
