But if she starts klling people, she will definetly be seen as a threat by everyone around her and the royal family. They have been leaving her alone because they believe she won't do anything bad but once she commits a crime, there really is no way to defend her anymore. There are already bad rumours about her and there are other countries and nobles that want any excuse to get their hands on her so it's not realistic for her to just kill them.
But is it really a crime if it's self defense? Especially if it's an assassination towards a noble, she's already seen as a threat so it shouldn't really change a thing, no one will be able to kill her either way not unless they have a death wish, honestly if she kills, people would be more hesitant to cross her
it won’t matter, the majority of the populace already sees her as someone to be feared, even if she kills someone in self defense it won’t take away from the public that she’s capable of killing someone, it’ll make her image worse and there would be even more people that would either want to kill her or abduct her and use her, could even threaten the people she cares about and all of this threatens the safety of people she cares about, and she doesn’t want any of them to get hurt at all

Girl, even Patrick says it's okay to kill so just kill those who tried to assassinate you, this obviously won't stop them from killing more people in the future and they probably have killed so much more in the past, also she definitely won't do this but she really should kill the maid, idc if the maid has a reason but if I were in MC's position, even if I'm strong, when a person who tried to kill me once especially if they were someone I knew, I'd kill them because that means they betrayed me even after knowing who I am, if they're stupid enough to try to do that, what's gonna stop them from doing the same thing again
