Every time Cassandra Clare tries to redeem Luke, she completely fucks it up.! Gretel is a part of his pack and looks how he talks to her. He treats her like she nothing more than a lowly servant. He never says thank you, never shows Gretel any gratitude or a bit of respect. I said this earlier about Jace, but this quote bears repeating:
“If you want to know what a man’s like, take a good look at how he treats his inferiors, not his equals.”
— Sirius Black (via J.K. Rowling)
I’m about one chapter away from being done, but I have to say Luke has actually surpassed Jace on ‘my most hated characters’ list. For all that I said about Jace, he is still a child. Jace has the opportunity to finally grow up and be a better person. Luke is a middle-aged man who refuses to change and grow up. Just take a look at his past, and what’s doing now. Luke took over the leadership role of his previous pack to use them simply as cannon fodder, then to only abandoned them when they became no longer useful to him. Then Luke stalked Jocelyn for years, then admitted to using his pack to stalk Clary, and now we find out how he treats the people he’s in charge of.
For me, Valentine is a homicidal megalomaniac, but Luke is just as a villain as Valentine.
