why I believe that Judas is a good guy:
-he buys her stuff
-he's trying to show affection but he doesn't know how
-he cares about her and says sorry
-he brings her to parties (if he didn't care about her and only used her why bother?)
-he seeks out what she loves and gives her what she wants (books, clothing etc)
-he looks after her in the most drastic times
-he reads her bedtime stories because she was scared
-he saves her from death A LOT of times
-we know, we know, "he abuses her" but it's only because she's trying to stand up for herself
-judas may sometimes be a little harsh but it was because of his past is why he's like that DONT BLAME HIM ALL THE TIME
-she loves him and she can't help it, judas is not a jerk, he's trying to show that he loves and cherishes her but he can't BECAUSE OF HIS INNER DEMON
-if someone can even find a light in the darkness, the one person who can help him, I believe that they are a good person
