Nicholas wasn't the most hated character of all time as he's been beaten outright by the Governor and now the Wolves, but since Glenn's demise he's giving them a run for their money. Viewers were shocked when Nicholas was responsible for Noah's death and he didn't seem at all remorseful; after all, Noah wasn't a part of his group. He then lured Glenn into the forest to try to kill him and this is when people saw him for who he really was, a nasty, cowardly excuse of a man. Without a doubt, anyone else in the group would have killed him in that situation. But Glenn chose to forgive him and even developed a friendship, regardless of how strained it was, meaning that Nicholas should be forever grateful for Glenn's kindness. And he did show that he was appreciative to Glenn as he mutters a 'thank you' just before he kills himself, but even in death, Nicholas proved himself to be a pain in the ass for our favourite Korean.
