Because he brazenly does things or says things that are hurtful but mostly he doesn’t actually want to hurt. He actually wants to help. It’s like he believes he is helping in his own way and doesn’t realize he is hurting the other person. Atleast that is the explanation from the novel. Even with chase, according to Greyson, he was trying to scare chase so that he starts taking out his pheromones through sex and not the extractor. Because sex is the best option. He thinks he was just trying to help Chase.
He’s not evil like how he’s potrayed in other comics and novels. The other comics and novels are from other perspectives so he s potrayed as a villain guy but in DMIYC we can actually see his true nature and he genuinely wants to help people. He was born as a dominant alpha . That’s a rare case in zigs omegaverse . They usually start Manifesting after 10 years of age but Grayson manifested during birth ( very rare ) which affected his brain’s emotional functioning . So he can feel emotions but can’t understand what emotions he’s feeling or what others are feeling so when trying to help he hurts others with his actions . And genuinely believes he helped them. He’s more autistic than a psychopath. People keep saying He’s a psychopath but he s not . He’s very much green flag to Dane in DMIYC. He’s consent proned . He has the best character development out of all Millers . Dane helps him , loves him and guides him in life . That’s why I love Grayson and Dane’s stroy in zig universe .

Can someone spoil the novels for me? Shy do everyone hates Grayson so much?
