I understand why everyone hates Renial at this moment, but in my opinion, this man has a typical borderline personality disorder, and his behavior is simply dictated by this fact. This includes his lack of expectations, impulsiveness, and fear of abandonment. Personally, I love it. I love that his "yandere" phase isn't something senseless or made for ratings, but is perfectly explained by his past. That doesn't justify his actions, but without it, the writing of his character wouldn't be so complex, and he wouldn't feel so alive. In modern terms, he just needs therapy.
What ML is doing is wrong, but I understand where he is coming from, he is not invincible, and he was made aware of it last time, the thought of losing Fl and perhaps his own life sure did some damage to his confidence- because, let's be real, this all is stemming from insecurity, even his possessiveness. He simply wants to be loved, seen, and treasured, just like anyone else...
So that´s why I personally am giving him grace, he is doing the best he can the way he thinks it´s the better way (it´s not, and I´m sure he will come to realize it soon)
Uhh, and I'm happy she mentioned he also ends up dying. Hopefully, that will help her change his mind.
