I'm pretty damn suring abusing your powers as a guild member and blacklisting someone for not valid reason without asking any higher ups gotta be illegal even in that world, so yeah she is a criminal.
why are you even defending her, she's just really trashy of a person, fine maybe she thought a civil servant was better for her friend as a lover but what was her reason for hating him actively and even going as far as blacklisting him for no reason? it's like she hated him with all her being.
funny how you say, "ig she just abused her powers, she didn't break any law" abusing your powers as someone in authority to ruin the career of someone IS against the law, even if it isn't written there there's something called common sense, not everything will be written by the author.
I'm not defending her. I'm actually defending morals, ethics, and actually, common sense. Being a shitty person, isn't illegal (And this is a good thing), no matter how many people want it to be. People are allowed to be shitty, and we can socially punish them. This does not automatically extend to using the government to criminally punishing people for being shitty. But even for social punishment, even Shitty people can suffer beyond what ordinary people consider Justice. Common Sense tells us, regular people shouldn't be the only arbiter of justice. We design laws from a consensus, for criminal acts to act as a framework, because ordinary people can be shitty too.
Common Sense isn't the Law. There's a reason, there isn't a Personal Vendetta exception to actual Laws. Common sense might say, eye for an eye and all. But real laws don't let you do that shit, because everyone has a skewed view of the "damage"/pain they've suffered and what sort of justice they're owed.
So, let's start with her punishment, she's been fired for misconduct. Not laid off, or let go for minor reasons, she's been shit canned. Before the severity of her misconduct even applies, how severely do ordinary people think she should be punished?
When she goes to apply for a new job, she either pretends to be a NEET for literal years(with all the stigma that implies), or embarrassingly lists the job she got shit canned for. If she tries to list her real employment history for any other job, she's going to need to say she was fired for bad behavior. Do people not understand how hard it is to find a new job with that sort of thing hanging over your head? Depending on how their system works, if a prospective new employer calls up the Guild, will they list the severity of her misconduct? How many people willingly want to hire a Shitty Person as an employee? Is that enough punishment? Probably not, but again that's a personal perspective not a legal one.
From the outside:
Ignoring all knowledge of backstory for anyone involved. Let's start from a clean slate. She knows, MC was just dumped by his Ex. For a "better" partner that she introduced (probably a good family, great employment prospects, solid salary). She believes he's a nobody that has been wasting his life being an unsuccessful adventurer and being poor (perspective of the ex, which is what she is going off of). With his Adventurer License deleted, he now comes into her orbit, with a young pretty teenager who looks and is exhausted, and is encouraging her to go into a dangerous dungeon to earn money.
Just looking at that, MC doesn't seem all that good of a person, right? He's possibly Creeping on an underage teenager. So, using this situation as the basis, is an ordinary person not going to view blacklisting a shitty person a good thing?
Once we have all the information, we can easily say she was the shitty person for doing all that. But again, that doesn't and shouldn't lead to criminally punishing anyone involved (a good thing).
