all of them are suicidal... out of the whole "lets poison the 31st consort" bunch everyone but one consort could be put to death quite easily for the mere attempt to poison another one...
the maid nele might be lucky or not but will need to die for this plan to work,
the head maid will definitely feel pain even if most if the plan stays hidden she is done in all but one event that her side succeeds and she can survive till sabrina becomes queen which might garner her the same position she is currently holding so she is risking everything for a zero sum game
and everyone at the table is gambling with their life and position at stake in case it gets found out they might not just loose the later but also the former but tbh who would ally her self with that snake... even if everything goes to plan chances are after she becomes queen she will hunt down her former associates just to leave no evidence behind and that possebility is obvious
@Moraza
yes if everything goes by the book he has to marry one of them but as the king he can change that pretty fast, a thought which he had already but judged that it would be a pain in the ass and not worth it... so while she can aim for it if its too obvious the king just might end the whole thing even if he doesnt put her on trial she will be done afterwards
so while im agreeing with your general conclusion i would also like to add that she cant make her tampering to obvious or she will still end with nothing but trouble, but that is currently her route
the planned poisoning of the 31st by a new maid that the head maid meddled excessively for to be assigned to the mc and was basicly born to be the scapegoat but has no motive and who needs to die before she can be tortured
even if everything goes to plan its so obvious that someone is messing with his decisions from inside his harem its actualy painful to ignore it
and if were speaking of the options a king has in general when he was forced to marry or wants to get rid of his current wife in favor of a new one i introduce "henry the 8th"
