Whose fault was it? (Season 7 spoiler)

So I saw a bunch of people on a TWD Facebook group’s page arguing about whether Glenn’s death was Negan or Daryl’s fault. I was honestly shocked at how many people took Negan’s side and said it was Daryl’s fault, because I always felt like Daryl was the victim. Like yeah, Negan claims he killed Glenn because of Daryl’s actions, but in my opinion, Daryl was understandably angry and as much as Negan acts like it wasn’t his fault Glenn died and that he HAD to kill him to get back at Daryl for trying to attack him, I think that’s false, Negan didn’t actually have to do crap, he killed Glenn because he was sadistic and wanted to see the Alexandrian’s suffer anyway. Plus it wasn’t like anyone literally forced Negan to swing the bat, which I think is enough evidence to absolve Daryl of any blame.
