I need to think before reading so Is ML very bad type of red flag guy ????

Oh no , he's worse . He's a black flag :')

don't rlly see what awfum things he's done till now? Like yea the mc's mum is dead and he ml seems to be the person that killed them all off, but we don't know if he killed her mum. It's not a black flag for me yet, there are way worse things that he coule have done

He R word him, broke two of his fingers, traumatized him, etc. He IS a black flag, maybe not to you, but in general he is.
